Needing to get a 100-amp sub-breaker box installed & wired at my house in NW Dallas in the next few weeks. Prefer to have it as close as possible to my current breaker box and have it wired for me to simply add the ongoing circuits to outlets/lights later. Current breaker is located in my finished garage. No idea on what something like this should cost, but I'll have cash to pay and/or guns to barter.
