Beer Tap Rental for Private Events

Since being here I have sought out this option numerous times, and since have a couple of personal options I can use. But I was thinking, since I had such a hard time finding the real thing, could others be interested in renting my tap system for parties and etc? I have a professional, mobile beer tap system that works for kegs with CO2 cannisters. It's always too expensive to have to rent the tap, then buy an entire keg, and the C02, plus the depos on all of these.

So I was thinking, is there any interest, from say people on this forum to rent a tap system, where they paid a fee for the tap/Co2, the weight of beer used, and be done with it(putting a deposit down on the system as well of course, for parties, events, etc?

I know from experience, if you try to arrange all this stuff on your own, the cost of beer is far more expensive then just buying bottles and putting them on ice. But, under my idea, it would either less expensive or on par, but it's always more kool to have your own tap. I tried to make this into a survey, but I don't see how to make that part of this thread work.

So, is, there any interest? And if there is an interest, any suggestions on what a fair price would be for a service like this would be? Without working out details yet like, who picks it up, should it be delivered, and so on. Thanks.
