Cost to remove an oral tumor?

My 6 month old Portuguese Water Dog puppy just got diagnosed with a benign tumor in his mouth. I can clearly see it and see that it is moving his tooth to a weird position so I'm not questioning the diagnosis. What I'm curious about is if anyone else has had this procedure performed on your dog. The specialist wants to take out three teeth and take out a small portion of jaw. From what I've read, this is the standard procedure for removing these kinds of tumors so they don't grow back. He quoted me $1500-$2500, depending on how long it takes and how Tino does with the general anesthesia. He expects it to be on the lower end of that scale, however. Any opinions on this cost? This is in the Washington, DC area so I expect it to be a little higher than somewhere in middle America.
