Does anyone have a good purchase contract template?

[Mark Brown]

I've taken some points from various sources and attempted to generate a decent purchase contract on my own for my first MHP deal. I have several "outs" built in, including a 30 day due diligence period, and how the offer is contingent upon me obtaining financing at terms acceptable to me...However, I'm worried that there is some clause that's being left out. Does anyone know of a good source for a purchase contract template without having to pay an attorney to draw one up? If the only option is an attorney, does anyone know the going rate for this? Many thanks.
