Los Angeles google map advertising

I am looking for a freelancer to help me with my project which is Los Angeles Google Map Advertising. I am interested in using Local Service Ads, so I need someone to set up a Google My Business account for me. As far as geographical areas, I am looking to advertise in several selected cities/towns within Los Angeles County. I am interested in exploring the different options available to me that will create the best ROI while targeting potential customers in the most effective way.
