Finish Shopify store

I started building my Shopify store but I'm overwhelmed with other things I need to do for my business. I want a simple store. Free theme. I started with the debut theme but I'm open to any theme. I only currently have 3 products. My logo is already done. I have my logo in Adobe Illustrator format. If you provide me with what kind of pictures and sizes you need I can provide them. I launched last weekend at a sidewalk sale and it went so well I need to get something up quick.
