Can you help me find an affordable bat removal service in Western NY?

I just bought my first house less than a year ago and I have bats inside! I did some research on bat removal services, but the only quote (through e-mail) that I was given was $1,200-1,900. I really can't afford that! Does anyone know of any affordable services in the Western New York area?

Answers:
Bat abatement is relatively easy. Find where they are entering the house. Usually through hole or crack near the roof. There is usually a tell-tale grey smudged area they leave behind from the oil on their fur. Staple a piece of screen mesh over the hole, leaving a long small tunnel with which the bats can use to get out. They will fly back to the hole but it will be blocked from entering. They are not smart enough to go back to the tunnel entrance to get back in.
Once you are sure they are all gone, cover up / repair the hole(s)
