Whole Sale Question on some wholesaling steps

[Seth Rouch]

I'm in talks with a deal currently and am needing to know more about my next steps. 

In simple steps ( I know there are other details, but these are my main questions currently)

Step 1 - Get seller to sign contract

-What kind of contract? Is this the same as the "Contract to Buy and Sell Real Estate" on DORA?

Step 2 - Find funding - still looking. I'm planning on wholesaling it out or purchase with hard money and flip (but that's more liability and expense)

Step3 - Closing - How does one close without letting each party know my profit? Or is this even possible?

I know different states have different laws - I'm located in Colorado
