LINK A PET

This program has not made me any money yet, but I am getting sign-ups like crazy. I have been working on a new site called LINKAPET.com and I hit a little road block. So now I am asking people for suggestions on how we can grow this idea. So here is the slogon   ADOPT, LINK, WIN CASH linkapet.com Basicly you adopt a pet (for free maybe), link it to what ever site or affiliate site you want, and get entered into a $100 cash contest. Road block then what? Should I go social, you just would use your "pet" as your picture, and start groups with other "like pets". Have an up-grade option where your pet can be featured on the home page, I mean the possibilites are endless. I do have an article that explains more as well, if anyone is intested. BUT, any comments about the whole idea will be great. Thanks!
