I need one of the two following:

a) to find a conversion kit that will work for my car with
instructions that someone with reasonable electrical and mechanical
skills could follow.

b) a service company in the Pacific Northwest (or at least west of the
Rockies, if they were really hot stuff) who could do this.

I can't spend a whole lot of money on this.  I need a product or a
service that is reliable and reputable.

You'll find some useful general info and lots of links in this flyer
from the Electric Auto Association:

Here's an EV conversion of a 1996 Geo Tracker. 

The good news: it can be done. 
The bad news: it took 600 hours and cost $9500.
