Buck and a half to two and a half dollars would be a normal range, plus or minus maybe a quarter. Lower end for normal dirt pressure wash and seal only, higher end in high priced areas or for wash, then restain first and then seal.

My recommendation - use a penetrating oil-based stain/sealer if possible (may not be compatible with existing sealer if already sealed once) rather than a high-body stain - high body ones peel relatively soon, and also lock in any water that does get in so you get rot.

BTW - the 'square feet" you are paying for are the square feet of wall being treated, NOT the "real estate" square feet of the house.

Normally a Painter would do the whole job - washing and painting, but be sure there is a LOT of drying time between washing and staining/sealing - log houses take much longer to properly dry out typically than plank, due to the cracks and the direct contact between the logs.

And of course, chinking and caulking has to be done BEFORE washing or you will be getting high-pressure water jetting in between the logs into your walls - or if unfinished interior - right into your house. Saw one house ruined that way - owner was not home during washing, came home to a few hundred gallons of water in the interior from the pressure washing blowing right through the gaps between the logs. Have to be exceptionally careful about pressure washing (as opposed to brush and hose) with chinked houses, because pressure washing can blast the chinking right out.
