hey weekend
I'd say CFI is your best shot now, unless you can find a banner towing job (you seem to have what they're looking for, tailwheel time + endorsment). Many will charge you for their training though, and it's only a summer job (unless you're in FL), but you can get maybe 400 in one summer season.
I'm now working as a 135 pilot, and got my min. hours by teaching first (yes, it's a pain in the butt, but very rewarding at the end and gets you lots of hours, quick). Most companies now require 1500TT and 200ME for 135 (I know, 1200 are min, but that's the FAR mins, not the insurance who are really the ones that set the minimums at any job). Most companies WILL NOT take any VFR pilots anymore (unless they're students from inside or buddies with the management). Not even AirNet does it anymore - and that was one of the main ways they got their pilots before 9/11. Think about it, a VFR 135 pilot is not really dependable for a company (schedule wise). Checks can't just fly on VFR days ... and if it's IFR out, they still gotta call the other guy to fill in, so why bother with two pilots if you can have one.
anyways, good luck with your job search
