Wholesale Assignment contract question

[Sean Wilt]

I'm clear on the how to write the contract to the seller to allow the option to assign the contract.  What I am not clear on is when I find an investor that is interested in being the assignee, how do I write the contract to them?

Is it a completely separate contract to assign the deal over?  so in the end there are 2 contracts? (one between me and the seller and another between me and the assignee?  Also, How do I disclose the assignment fee to the assignee?  For instance, if the agreen sell price on the property is $100k, Is the contract between myself and the assignee just for a straight say $5k?  and then I'm out? 

Hope this makes sense, just starting out!
