Shopify print on demand app

Hi,

I created a store where people can personalize products like:
Art & Wall Decor
Bathroom
Blankets
Pillows & Covers
Mugs
Stationery
Magnets & Stickers
Pets
And Other

My idea is to create more than +1000 different editable products like custom mug with custom image and text and then sell it and create shopify app with these products. Everyone will have an option to install each our product on their shopify store and we will charge for each order.

You can check my store at below link:

You can for example go to mug product, add own picture and generate own mug with own picture. But products added at my store are very basic, nothing special. I need someone who can make very good customized products and who is interested in long cooperation.
