Toll roasting is not very common around these days but I am sure you can find someone to roast them for you.
You need to find some artisan roasters.
If its not way too much, it won't be too bad but if you are running a business, you could negotiate with roasters.
Do you have tons to roast or just for your home use.
I know few people out that way but if you give me specific location, I could look and see. Also if you say West Coast, that is very large area so I think being more specific on the area will give you some positive reply from our members as well.
