So as I've never done a fishless cycle before I've decided to make this thread and keep the post updated with my daily test readings and how much of what I'm adding for Ammonia.
Unfortunately this won't be a complete log from the beginning as I took faulty measurements the first few days, and for two days before that was erroneously adding bacteria.
So here's my reading from the start of where I've got accurate measurements:
Tap: pH; 7.6, Ammonia: 0, Nitrites: 0, Nitrates: 5-10
Day 3: ph: 6.6, Ammonia: 0-.25, Nitrites: 0, Nitrates: 10-20 - Added 1 big pinch of fish food & 1 small pinch of fish food
Day 4: ph: 6.7, Ammonia: 0-.25, Nitrites: .25, Nitrates: 20-40 - Added 2 big pinches of fish food
Day 5: pH: 6.6, Ammonia: 0, Nitrites: 1, Nitrates: 40-80 - Added 1 big pinch of fish food
Day 6: pH: 6.7, Ammonia: 0-.25, Nitrites: 1-2, Nitrates: 40-80 - Added 1 big pinch of fish food
Day 7: pH: 6.8, Ammonia: .25, Nitrites: 1-2, Nitrates: 80 - Added 2 big pinches of fish food
Day 8: pH: 6.6, Ammonia: .25, Nitrites: 1, Nitrates: 40 - Added 2 big pinches of fish food
Day 9: pH: 6.6, Ammonia: 0-.25, Nitrites: 2, Nitrates: 80 - Added 2 big pinches of fish food
Day 10: pH: 6.8, Ammonia: .25, Nitrites: 2, Nitrates: N/A (test tube accident, broke) - Added 2 big pinches of fish food
Day 12: pH: N/A, Ammonia: .25, Nitrites: 2, Nitrates: 80 - Added 2 big pinches of fish food
Day 13: pH: N/A, Ammonia: .25, Nitrites: 2-5, Nitrates: 80 - Added 2 big pinches of fish food
Day 14: pH: N/A, Ammonia: .25, Nitrites: 2, Nitrates: 40 - Added 2 big pinches of fish food
Day 15: pH: 6.8, Ammonia: 0-.25, Nitrites: 2, Nitrates: 80 - Added 2 big pinches of fish food
Day 17: pH: 6.6, Ammonia: 0-.25, Nitrites: 2, Nitrates: 80 - Added 2 big pinches of fish food
Day 18: pH: 6.8, Ammonia: 0-.25, Nitrites: 2, Nitrates: 80 - Added 3.5ml 10% Ammonia
Day 19: pH: 6.8, Ammonia: 1, Nitrites: 2, Nitrates 160 - Added nothing
Day 20: pH: 6.6, Ammonia: 0, Nitrites: 2-5, Nitrates 80-160 - Added 3.0ml 10% Ammonia
Day 21: pH: 6.8, Ammonia: 0, Nitrites: 2, Nitrates: 20* - Added 3.25ml 10% Ammonia
Day 22: pH: 6.8, Ammonia: 0, Nitrites: 1-2, Nitrates: 20* - Added 3.25ml 10% Ammonia
Day 23: pH: 6.6, Ammonia: 0, Nitrates: 1-2, Nitrates: 160 - Added 3.25ml 10% Ammonia
Day 24: pH: 6.6, Ammonia: 0-.25, Nitrites: 1-2, Nitrates: 80* - Added 3.25ml 10% Ammonia
Day 25: pH: 6.6, Ammonia: 0-.25, Nitrites: 1, Nitrates: 80* - Added 3.25ml 10% Ammonia
Day 26: pH: 6.6, Ammonia: 0, Nitrites: 0.25, Nitrates: 80* - Added 3.25ml 10% Ammonia
Day 27: pH: 6.6, Ammonia: 0, Nitrites: 0, Nitrates: 80-160* - Added 3.25ml 10% Ammonia

I get it that Ammonia Chloride would be a more precise additive for ammonia but I don't have any and don't have much money at the moment so I'm using fish food. Might pick up Ammonia Chloride in a few days or a week if the tank is still cycling then.
Feel free to give advice, suggestion, really any kind of feedback.

Updates:
Do responders get notifications when I update the first post of the thread?
Don't know how day 8 read less Nitrates than day 7. There's nothing that should be consuming Nitrates in the tank ATM.
Day 11 I neglected to test... was slightly disheartened by the loss of a test tube.
Day 12 I decided to leave out the pH and test the Nitrogen cycle.
Sorry for no updates for the last few days.
Finally got ahold of some Ammonia on Day 18. Will be using it instead of fish food.
Okay the fish food I was adding must've been a good deal less potent than I thought given the 18-19 jump in Ammonia. I was thinking things would proceed as usual.
Day 21 originally read 0 Nitrites, this was a typo, the reading is now correct.
Okay I believe the Nitrates readings with astryxes are incorrect and rather than being low are off-the-charts. I've decided to mark them and report what the test says just for the sake of having the readings in case something screwy is happening.
Day 27 it appears that the tank has finished cycling!

You don't need ammonia chloride, you can buy plain ammonia from a hardware shop and use a few drops of that. Just make sure it's only ammonia, so check the label.

I've lost my notes on what I'm looking for to tell if the tank is cycled... could someone please fill me in on that?
Also once the tank is cycled how would I go about maintaining that without fish? I want the tank to mature so I can introduce shrimp before fish.

When the tank is cycled the ammonia and nitrite should drop to 0 within 24 hours of adding enough ammonia to raise the ammonia to 2.0. To keep it cycled add a few drops of ammonia each day to feed the bacteria.
Once cycled you are likely to have nitrates that are off the scale so do a number of big water changes to reduce these to a sensible level ( I would aI'm for under 10 ). Do the water changes before adding the ammonia so you don't end up removing the ammonia you've just added.
It's common to find nitrates so high that it takes a few large water changes before the test shows any change, this isn't a sign it's not working only that the level is so much higher than the test can read.
