Not sure that I understand completely. If you are asking can someone find venture capital and how should I compensate them, this seems like one of the more acceptable formula's:exitpromise.com/lehman-scale
Not sure why you couldn't have a conversion to stock equivalent to the Angel or VC's investment rate hence if the angel and you agree $100 is .01% there is no reason why the 'money raiser' cannot convert equally.Actually an angel may be more comfortable with that.
The person raising the money however is going to have to disclose all this to the investor and it should be in the offering document as a prominent feature.You wouldn't want the money raiser to leave that to you and you don't want to waste time meeting Angel's or VC's who are in agreement or knowledgeable about how some portion of the cash they are about to give you is going to be used.
Regardless there has to be a timeline for performance so you are not forever waiting for funds. Anyone who wants cash up front for raising cash that is not yet there probably is not the person you're looking for given your description of the venture.
