1) you get your shares right away but they are restricted until you put in your 1000 hrs (this might be best because it starts the long-term cap gains clock ticking)

2) you get your shares in 1000 hrs (i dont like this. what if he raises money at a 20mm valuation. you might have a serious tax implication). This is a form of vesting.

3) the 1000 hours happen and then you get your shares over time (vesting) after that

4) all of the above, but you get options instead of shares. Not sure if I like this either but depends.

But all the other things I mention (anti-dilution rights, non-competes, change of control, change of responsibilities, etc) are all very important. you can't do a deal without everything spelled out.
