Opinions Needed! On my store and how to close sales!

I have had my store up and running for a little more than a month! I haven’t made any sales yet-

I am interested in feedback, what do you think of the site? www.mrmmediocrates.com

What changes can I make to close more sales? Better copy? Imagery updates? Anything?

Also, what apps are recommended to get marketing done for you? I’d prefer something with a 30-day free trial, I have sunk all my beginning capital in creating products and other business expenses, so I need something that will drive some sales for me? Any suggestions, I can elaborate on my needs if clarification is needed
