Wix Website development and print on demand services

Hello,

I have built a basic website for my business using Wix to sell seeds and merchandise. Eg. T-shirts, bags, mugs etc

What I need;

1. I need help to finish the website and make it more professional so I can launch the online business.

2. I need all of the products to be linked with print on demand services.

3. I need some tutoring to be able to maintain the website and understand how the print on demand services work.

The website is currently live and has approximately 200 products showing as 'out of stock' because I haven't connected any of them with a print on demand service.

I have just made 100 templates using Printful and Etsy but realised I need some help to finish the project.

Please check out the website to see if you can help;

I have suggested a budget of £120 but I'm open to suggestions.

Thanks for your time.
