Not a regular chandlery but a place that specializes in boat wiring. Ask them, be willing to pay to get them on board if they think it is worthwhile. Even if you do the work. I have seen some dangerous wiring done by folks with good intentions, good mechanical aptitude but incomplete engineering. You clearly want quality work, having an expert pointing and directing 'on site' is awsome. Annie and I went to the Bellingham City Council meeting tonight where they discussed last month's marina fire with 2 fatalities and 12 boats lost. Hope this helps, fair winds.
