Need to get 3 things -- where to begin!

We have 3 big things we need to buy, but doing the research to find what we need at a great price is a lot of work! 
Where to begin?!

We need to buy:
1. King sized mattress with king sized bed frame and bedding without breaking the bank.  The mattress must not jiggle when someone shifts in the bed.  The bed frame must not creak when moving in the bed. 

2. A good steam mop for under $100 that doesn't damage hardwood floors.  My Swiffer just pushes dirty gunk from point a to point b.

3. A guy to spray our house with poison (without killing Caitlin and the guinea pigs) since I'm sick and tired of ants, spiders, and mysterious creepy crawlies invading our home (see photo on the right).  The last time we got our house sprayed, we paid $30.  I would like something in that price range again.  =]


Please send suggestions my way.  =D
