I may get flamed for this but, LMAO your not serious are you I mean, you want people that have spent their valuable time and money gaining clients and many hours already on support for the same clients to hand them over to you and they get a generous 30% for their troubles, sounds like you are trying to get some one else to get you clients.

Have you heard of affiliate programs, you can do the same thing and offer your affiliates 30% for gaining clients for you.

I would strongly advise against this offer to any one that is serious about becoming a reseller and/or moving on to becoming a full hosting service provider, as it is simply a glorified affiliate program.

If you are looking at becoming an affiliate then go for it.
