It sounds pretty clever. I'm not certain that it's a problem to be solved however unless someone is trying to access a professional and have not been successful in doing so for whatever reason. I would suggest figuring out what other web-based networking sites aren't providing that your website would. For instance, what gap would you fill that say LinkedIn isn't? And another important question is who your target professional is. This might be attractive to Millenials but not so much with Baby Boomers. I hope this is helpful.
