Looking To Buy Property For $90,000, No Money Down

Hi DG family, I have a person here in my city of Fairfield, Ca. who needs me to find him a property
out of town for $90,000 and zero down to own. Guess you can say I'd be bird dogging for this person and he said it doesn't matter how many bedrooms or even just one bedroom is fine. I have thought of contacting some real estate agencys here in town and looking to find one in this price range.
Please someone who has had the experence doing one like this, fill me in on exactly how you went about it from start to finish?
It would be my first deal and I can't put up the money
myself, so it would have to be 0 down. Wouldn't I put buyer and seller together and see how it goes? I could
really use any advice how one of you more professional's would go about this from start to finish.
I also made copies of all forms on Deans site and looking up that type of property would be faster on the internet of course.
Would appreciate any professional input from other investors in here.

Thanks much!
