You are making it too complex. Write a contract with each. When one contract is completed to your satisfaction tell the other guy to start. The two can talk and coordinate with each other,too.
For a job that small you might not find guys willing to put up with a lot of bs in a contract.
you might be correct. I might heed your advice and take the scheduling hit.
the scheduling hit is probably better than any of the alternatives, all of which seem less palatable at the moment.
thanks for the input.
