I've used Harlan recently (with rabbits) and have been overall pleased.
I think they will do Guinea Pigs- check their web site. They will
provide pre-immune bleeds for testing. These used to be free (at least I
wasn't charged several years ago for this), but now they do charge a
small fee for this (I think I paid $10 per for them). On the flip side,
they held a rabbit I wanted for a few weeks with no charge.

Also, you might want to check on shipping and dry ice charges. These can
end up being rather high, so you should factor that into cost
