Looking for an electrician to replace our original 1950 meter base (and probably weatherhead and conduit between).

They need to:

Answer the phone or reply to the voicemail I leave (tons of tradespeople/companies can't handle even this simple request)
Be licensed, bonded, and insured
Work in OKC (NW 36th/May area)
Show up on the day they say they will if we agree they'll do the work

Thanks in advance for any suggestions.
