Well. Not every company is going to bid on every location. Just the ones that suit them. Also, 150 companies have not signed up yet with this site. I just have 150 plus other companies I have dealt with in the past with (my) other sites.
To clarify, 30,000 hits, are not equal to 30,000 uniques. I get several hundred uniques for the month, but again, the site is brand new. about a week old.
I think I have decided at this point to allow free accounts by colocation firms and datacenters, until the traffic and membership gets ramped up. I'm just going to change it to my regular brokerage fee on closed deals. Your initial Feedback here, has helped me with that decision.
Later On down the road, I may go back to a membership model but until then, I'm going to open it up.
@Michael McRae. One closed deal could pay for the membership for a year or multiple years. So far had about 5 requests (you can see them on the site). But... since i'm not charging for membership now, it makes no difference.
