Need an investor friendly brokerage to hang my license

[NA Jones]

I'm a licensed agent and investor currently with Keller Williams, but I'm getting sick of paying their monthly fees.  They've been great so far, but I don't want to work with "retail" real estate clients.  I only plan to do approx 6 transactions per year, at least 4 (if not all) of which will be my own transactions.  Can anyone recommend a good brokerage that will let me hang my license and not charge me $25-75 per month (or annually) in fees?  I just want to quietly do my own thing and not pay through the nose to have my license hung.  I'd much rather pay per transaction.
