Any decent size IT services (or Managed Services Provider) can or has someone's contact info on hand for this sort of thing. Security camera vendors also do it all the time, so they would likely be able to do it.
Don't be surprised though if there's a service call + $85-150/hr. for a single run. In OPs case, a MCOL area like the one we service should have been about 1/4-1/3 the total cost even for a professional low voltage shop.
