Oof. Ummm... No.
Ask around for a recommendation for a really good local computer builder/ computer tech. The really good ones hang out their own shingle, and won't be found in the eek squad (that was a pun, not a typo).
A one-horse guy will be reasonably well rounded, capable of running wire, working on the boxes, setting up security, etc, and will be able to advise you as to what telecom services you really need.
OK.
How can I tell if one is good. I hired a guy last year to clean up my computer and save some data and 800 dollars later I find he was marginal at best. And he came well recommended.
