Does somebody have experience with GoBIG network?

Because of the modeling portfolio site that I plan to launch I started to look for investors and I got across gobig. One time fee would be $176 and there are investors with bucks. I just need some accessories and a studio place to lease for which I have no budget at the moment. I’m not sure if these networking sites really work are they are just waste of time. I registered anyway for free, but to list anything I need to upgrade my account. Is it worthwile? Does it pay back? Any ideas how to get investors into new startups?
