Ask HN: Can I see your vesting agreement?

My partners and I are about to incorporate and we want to put a vesting agreement in place.

We've got an accountant who will do everything for $500 (S-Corp filings, vesting, articles of blah blah). Still, if we do it ourselves, we only pay the state fees of $150, saving $350.

But, I've never put together a vesting agreement before. Previous ventures were partnerships where we split equity up front.

So, does anyone have the legal docs necessary for creating a vesting agreement? Or, should I just pay the money and have the accountant do everything?
