Need Help DC area VCR Betamax

[rodmonster]

Does anyone live in the DC area and work on VCRs? Generally I can make my own repairs... Although they are basic for belts gears and cleaning.. But I have 3 right now that I can't seem to figure out. and I would really like to get at least two of the three working well.

One is a Betamax VCR and the other
two are top loading VHS VCRs. The betamax allows the tape to
go in but will not play and I cannot seem to get to the
motor under the cassette rack. One of the other two VHS VCRs
allows the tape to load but the feed reel will not turn. I
know it's missing at least one belt... But it may just
be the counter. The third VCR .. the video head seemed to be
dirty and while cleaning it I noticed one of the wires on
top had come loose. While trying to tighten everything back
down the others came loose as well. I did my best to solder them all back together. But I still only get noise on the screen and very little volume now. I can supply model numbers if need be but I really need somebody that is willing to work with me on this and not charge me an arm and a leg to get them running
