Wordpress WooCommerce Lumise designer to Printful POD Integration Specialist

I'm seeking an experienced freelancer to set up Printful integration with my Wordpress WooCommerce store using Lumise. Site is started so feel free to visit and review. I need it to be 100% done. Expect 100% automation, from site designer to order, to Printful order to customer, including tracking.

Essential Tasks:
- Automatic order fulfillment with designer
- Product sync with Printful
- Lumise integration for customer product design
- 100% automation
- order tracking
- designed images in final checkout
- cart shipping totals are in line with estimates from Printful

Ideal skills and experience:
- Experiance with WordPress
- Expertise in Printful and WooCommerce
- Proficiency with Lumise
- Strong background in POD setups
- live sites using same tech and references from site owners

I've seen sites that load the cart with the designed image, using the exact same configuration I have. The last developer I had could not figure out. I have not progressed the site since he last touched it. I purchased a full copy of Lumise. I'm looking for website development work for POD. Looking to put designer in the hands of the customer so the order is fulfilled by Printful using Lumise, I need to get this thing done. I need to know, are you able to deliver to the checkout cart the images created in the designer of the products the customer designed. I was burned by a developer over promising, and I need to know if you can do this, I see it on other sites. I will require samples of your work using this exact combo (urls in production only - no portfolios only functional sites) along with details of the stack and tech you used on each site, I'll recognize BS so please dont waste my time. Currently, I host on wordpress, using woo, and have a growth Printful account with Lumise installed. Have flatsome and some mix of templates, I'm not happy with the mess of I site that was created. I want pretty models, better pictures (no crap AI cartoons). I need to simplify the products and correct the pricing on products and shipping as well as make sure embroidery and color options are clear and selectable in some format better than the dropdown it has. Attached are pictures that point out the items I want removed or changed.
