The Kindness of Friends?- ISO Car with a ball hitch

I really need to get my motorcycle up to Londonderry. I can rent a trailer from U-Haul for 15 bucks a day (woo!) But I don't have a hitch on my car. To get one installed w/ all the fixings the adventure will cost a bit over 300 bucks. While I'm cool with the idea of a permanent hitch on my car, I don't really want to spend that right now.  So! Is anyone able to help a motorcycle babe out? Bribes/reimbursement within reason are of course on the table.
