First off,i don't know if this is the right place to place this but here goes.
i have a contractor that wants to lease 2 cameras from me to watch over a construction site next to the Condo unit i am doing for him, (for about 5 to 7 months)does anyone have a lease for this or could help me make one up?

lookup "lease" in the yellow pages of your phone book and tell them what your wanting to do. They should be able to take care of all the paperwork and liability.

No sense in re-inventing the wheel........

this is something i am doing for free for a friend didn't really want to spend the money since i am down with a broken hand now, this really sucks.

The lease won't cost you a thing, they will work the interest into the paperwork and spit out a monthly number for your friend to pay. Its a very harmless process.

Pickup the phone and see what you can find out, I think you'll be suprised.

There are people that lease portable systems designed for construction sites. One place to look is www.remotesystems.us.
