Well, as a suggestion, you should certainly ask yourself what it SOUNDS like from the perspective of someone hearing the name for the first time, and work from there.
From my perspective, it appears to be a business that allows me to "shop" for "cash". At once this sounds outrageous, but there are many businesses models that have been built on the notion of doing odd yet inventive things with existing mechanisms. So, HOW would it be that someone visiting your website could shop... and put money in there pocket at the same time?
CONCEPT: Make Money as You Shop!
This is the next part. Affiliate programs have been hugely popular, and many have provided great ways for websites to make money, while directing people to their business. One thing a friend of mine did once (that I've seen more than a few times), is ask me to set up a store for him, so he can benefit by getting a discount on his own purchase.
CashCart.com could make this type of dynamic a reality for a wider audience. People set up a membership, and buy products through CashCart's dynamic affliate system. CashCart could sign up for a large number of merchant affiliate programs, and as members click to buy products through CashCart, CashCart can record its sales, and show the customer how much their CUT will be. Payouts can be arranged nicely.
Also, CashCart members can use CashCart's "revolutionary" search engine service to click through to all sorts of great services, and sign up. Next to EACH directory listing CashCart can list the amount the customer could get-BACK if they purchase products/services from that vendor.
CashCart could in effect PAY people to find and use great services. People could suggest new services to be added to CashCart everyday, and CashCart can track and report the pay-out. Meanwhile, CashCart allows members to monitor what they think their payouts will be, and CashCart will automate as much of it as possible.
One idea. Certainly seems compelling if I saw it somewhere. I'm sure someone is doing it already in some flavor. Beanz (now defunct) worked to do this, but nothing beats the allure of cold hard cash. Just make sure you have disclaimers for non-paying dead-beat affiliate programs and be as forthright with the membership as possible (have a forum).
Lots of footwork, but it might be a hit if you can find a software/interface/feedback model that works.
