Airportdiscountparking.com will do Avistar at $78 for a week, plus 13.80 for each additional day plus tax.

longtermparking.com will do $14 a day (with tax) at the dollar lot.

parksleepfly.com usually is something like $125 for a room and seven nights parking.

There are people who park on the street, though I wouldn't do that.

I believe the last time I was there the Clarion across the street had a banner up saying they were $13 a day, don't know if that includes tax or not.

By the way, those outside lots can fill up, so make sure you clal to see if you need reservations.
