Need a Data Analyst For Building KPIs and Help me Analyzing my Browser Extension Business

I have a Chrome extension and I do media buying for getting new people to install it. I have Google Analytics setup and everything is tracked. However, Data analysis is not my area, and I'm having trouble to find the most profitable zones, to calculate potential ROI, creating metrics, etc. I need a freelancer help for that. If you have past experience with Data Analysis or think you could help me with this, please PM me with your proposal. We can negotiate price.
