Speaker repair crossovers for Mission

I have a pair of Mission 765 speakers. The speakers don't play full sound unless there is some pressure on the binding posts. I suspect that some crossover work may need to be done. If I am going to go through the hassle of fixing anything, I'd probably prefer that someone rebuilds the crossovers with some fresh caps, etc.

Do you have any recommendations for a company or private person that I could send the crossovers to for repair? If the company happens to be in South Florida, I could just drop off the speakers themselves.

Thanks!
