Colorado Wholesaling using the full 18 PAGE Contract?

[David Sanchez]

I'm looking for advice from experienced wholesalers in Colorado.  My attorney sent me a document for getting properties under contract with sellers and it's the essentially the full 18-page Colorado Contract to Buy and Sell Residential Real Estate.  I am just getting started and imagine that it will be extremely difficult to get sellers to fill complete an 18 page contract just to agree on a sale price.  

Does anyone have experience with this?  Is it difficult to get sellers to complete the 18 page contract...?  Or is there a shorter version (1-3 pages) of a buy/sell contract that can be used in Colorado?

Please help!  Thanks in advance for any replies.
