Antonio - You sound brand new to Wholesaling.
Please excuse me if what I'm about to state seems obvious but I cant tell where you are in your wholesaling business.
Have you built a buyers list? @ the very top of the wholesaling forum is a sticky entitled Buyer's List "How To".
Its a good read and will essentially give you a crash course on one of the main staples of a wholesalers business which is finding buyers for properties you put under contract.
In fact, the entire wholesaling forum would be of great educational value to you if you are a newbie.
IMHO @ a very high level your wholesaling business should look like this...
1) Market for wholesale properties. (probate, REO, craigslist, FSBO, bandit signs, etc.)
2) Put wholesale property under contract.
3) Consult your buyers list of cash buyers for interest in heavily discounted wholesale property.
4) Assign your contract to cash buyer / rehab investor from your buyers list.
5) Repeat.
There is plenty of detail in-between but you will learn as you go.
I dont know about any other wholesalers but it took a while for me to get this right. It sounds simple but I had to keep trying until I had all the pieces working together.
It may not happen instantly for you but it will happen if you keep at it.
At the end of the day as a wholesaler, you gotta have houses to sell (at a heavy discount) and someone to sell them to.
