I'm betting Rob's tutorial will be great.
Lots of plans for flemish jigs on the 'net--be sure to pick one that goes by ACTUAL STRING LENGTH--lots go by bow length, and that is always hit or miss.
If you aren't mechanically inclined (I'm sure not), BCY has a nice little set-up for endless strings that doesn't cost nearly as much as the "Dream Machine" jig (that's what I have--it's a great jig, but expensive). They have the uprights without the uni-strut bar that you can clamp to your work table--not quite as fast or convenient, but lots cheaper. If you need info on that one, just holler.
