There is no specific surveying license, those names you mention are affiliations to credit passing a course. I'm not sure about the costs out your way. Out here $15-20/foot is normal.
Also, FYI the E32 I was looking at 2 years ago was priced at 14K and was mint.....but had the gas engine. From the research I did back then, that price was fair. I would think it would be down a bit now. Go for it!!
