8 or so leads a day is roughly ~2700 leads per year. A $20k budget means you can spend about $7.50/lead. Depending on your niche that is likely going to be difficult to do with adwords alone.

Again depending on your niche, Thumbtack might actually be good here. In my experience though Thumbtack is very hit or miss from the businesses side of things. If you're spending $5-$10 just to send an email to single potential customer it might not be cost effective.
