where to get a bike and guide in PP?

Dec 28, 2005
2 of us are looking to rent 250 xr's or the like in Dec, out of Phnom Penh. would also like to get a guide for a couple days of a 3-4 day loop. NOT looking for a package deal, just want to roll into a shop like in Chiang Rai and rent a bike, then have the owner call up a dude who speaks enough English and knows the area well enough to show us around. as i recall 3 years back in Chiang Rai, guide was something like $25 day plus we bought him food, beers at the end etc.

want the guide so as to help us find fun and suitable off-road action for a couple days, then ride the more obvious parts on our own

any ideas as to what shops are most likely to have the bike/guide combo?
