Where can I find serious legitimate wholesalers in Massachusetts?

[John B.]

So far with the very limited networking I have done, I seem to only find new wholesalers that are just getting started, but never really have done any serious wholesaling.

Where can I find those wholesale folks particularly in the Massachusetts area that are investing heavily in marketing and actually have a steady stream of wholesale deals that they send out to cash investors?     Ideally multifamily wholesale deals...  

Are there lists somewhere?   Online sites with serious wholesalers?    I do occasionally attend my local real estate groups.. but at the time wasn't actively looking to purchase more properties, but now I am ready to purchase more multifamilies.

Any leads at all would be greatly appreciated.
