All we need is a website guy and a site along the lines of johncurriehatesemaw or something like that that features plain, direct points of why he's horrible. Not exclusive to Frank/Weber issues. There have been plenty of manifestos posted in the last few weeks to draw the points from.
That takes like, no money.
Once that's done, and you have something to put on a billboard, you price it. Somewhere in here were volunteers and contact info for figuring that out, at least in Manhattan. If it's truly $350/month - that seems low, but say it's even double that - I doubt we need a convoluted paypal fundraising effort. That's a handful of people throwing in to get the billboard up ASAP.
From there, raise money as needed.
Contrary to what you might've heard from bosz56, I don't know crap about making a website, and I don't have the time to write out the verbage for the site. However, there's the needed steps. People who were talking about doing certain things before, if they fit in this process, go ahead and do them.
