How do attorneys typically charge for creative financing documents?

[Brian Huber]

Hi, I've contacted a couple of attorneys stating that I'm preparing to launch a direct mail campaign and there (hopefully) will be leads which I'll want to do Subject To or Seller Financing transactions.

I asked the attorneys how they typically handle these and they stated that once the deal materializes, that they can draw up the paperwork.

Is this the case for others? My concern is that I'll be paying a big chunk to an attorney per transaction which will definitely take away from profits.

Should I be approaching them in a different way?  I figured that once they draw up the paperwork, I can apply it to multiple deals and tweak minor details depending on the situation.

Any thoughts on this matter from the pros would be greatly appreciated. Thanks!
