Why don't you try to DIY? Don't you have any savvy friends?
If you can do the hard mechanical/installation part, electrical repairs aren't that mysterious or difficult. Firstly, get a good manual on your Honda engine and an inexpensive electrical volt/ohm/meter. Secondly, separate the engine wiring from everything else. Then separate the lighting from everything else. Then separate the turn signals from everything else. Tag all wires, take pictures and take notes.
Looks like a $1,000 repair bill from the electrical shop, but you can do it for less than $50.
You can do it; you have nothing to lose. Just don't cut or shorten any wires until you get each system working.
