Google AdWords Setup for App Installation

I require an experienced freelancer to set up a Google AdWords account for my business. I'm specifically interested in running ads for app installation to boost my application's exposure. Ads should focus on both Google Play Store and Apple App Store platforms. Though the target audience wasn't specified, insightful targeting is a necessity. Ideal skills would include expertise in Google AdWords, proficiency in digital advertising, and a strong understanding of both Android and iOS marketplaces. Experience in audience targeting, even with limited information, is an added advantage.
