No need to pay someone like Local Adlink to do this for you. You can do it yourself easy and save the $70 per month. I spend way less than that each month to have our ads pop up on website via Google Geo targeting ads.
But I'll warn you, geotargeting ads don't produce a lot of calls. What really produces a lot of calls is being on top of Google in the organic listings. Type in "landscaping Portland Oregon" into Google and see who's site comes up on top in the regular (organic) results. That's what produces calls.
