Totally new to the boards, relatively newly engaged

I'm looking for sites for ceremony and location in the greater Seattle area. We're hosting it ourselves, estimating about 100 guests, and our budget for site+rentals (tables, chairs, linens, etc) is about $1500. We're getting married August 2012, hoping for an outdoor ceremony, either indoors or outdoors for reception.
We've checked out Tracy Castle, was a nice facility but the used-care-salesman pitch asking us for a deposit before even getting to look at the contract drove us out the door pretty quick.
We've also looked into a few other sites that look lovely but seem out of our range. I fantasized about Mountain Springs Lodge in Leavenworth, but too pricey I think and it'll be a decent ways to travel for our out of town guests who are mostly coming in from the east coast. I was impressed with Robinswood House, but again it's out of our range.
Right now I'm looking into Druid's Glen golf course / Fire Creek Grill in Kent/Covington area. Anyone have experience with them?
Other options we're looking at: Point Defiance in Tacoma, a ceremony at Discovery Park in Seattle with a reception somewhere else, things like that.
Any other ideas/suggestions for a newbie knottie?
