This is a great idea and I am glad people are interested in what you have to offer. I am sure this point has been brought up but not everyone has PC building knowledge/time+patience/will to want to set up dedicated mining rigs. As investors in mining they simply want to throw money at something and make magic happen, which is what service you provide.
If you do end up cranking up sales and getting more people involved let me know - I'll shoot a PM your way.
