Digital Marketing Expert for Website

I am in need of a digital marketing expert to help me promote my website. The primary service I am looking for is PPC Advertising, as I want to get the most out of my budget and maximize my visibility on search engines. My primary goal for this project is to generate leads, so I will be expecting the services to include keyword research, website optimization, and AdWord campaigns tailored specifically to my needs. My budget for this project is less than $200 and I'm looking for an experienced professional who can deliver quality results.
