Uploading to Printify and Etsy Listing Refinement

Hello! I have a very successful mask shop with almost 1500 sales since last June. It has been a handmade business so far. Very experienced with Etsy, but this is my first time using any POD services. I have about 25 designs ready to be uploaded to Printify (not Printful) for POD t-shirts (and eventually other items) I’ve collaborated with an artist/designer on these designs so they will be ready to go. I’d like help uploading everything to printify and making sure I have all of my options – sizing (womens only) and color options in order. When I integrate with my Etsy shop, I’d love help refining the listing that will have uploaded from Printify and also will need to get some nice mockups – which I can create, I will just ask to make sure I have them in the correct sizing/format. Please let me know if you have ever worked with Printify, as that is a requirement. If you’d like to take a look at the quality of my shop (still featuring only masks) you can do so at: shesspeaking.etsy.com We have a few bestsellers and are doing really well in our category of womens empowerment/diversity, etc… I believe some of the data provided by our SEO and most searched keywords for masks would be helpful and might carry over into keywords used for the t-shirts. We feature iconic, highly searched women such as RBG, Kamala and others throughout history as well as messages of diversity and equality. Our shop has been doing pretty well and we have many loyal customers who want to come back and purchase items other than masks from us.
