Hey Jensen,
You have to be very careful with Google Adwords. I'm in Denver which is announcing a new coworking space every two weeks and competition is high.I just spent $150 in a single day because are CPC is around $25 when search for offices. Granted, this can be very valuable if you hit the right person but you have to know that it will take a lot of money. You might want to look into cheaper keywords or work with a company that might be able to position you to have lower CPC, but it sounds like you are doing that yourself.
For ads, my bounce rate is twice as high compared to organic search.
If I was spend money on ads I would focus more on Facebook with my CPC as low as $0.60. I can get 100 people to check out my site for $60 versus the two to three for Google. Yes, the Google traffic is targeted but the numbers are so much less. Test it out and let us know what you find.
