$250 sounds reasonable to me... You might be able to do cheaper over the winter when these sorts of businesses are slower and need the work.

Not a real hard job if you are handy and patient. You just need to be sure and route the wires where they will not chafe, make sure your connections are made to a place where you won't get interference and you seal any wire connections with heat shrinks to avoid corrosion.
