Integration of a store on WIX.COM with InPost parcel machines and BLIK payments

Good day,

I have an online store based on wix.com. Unfortunately, it turned out that this platform is not integrated with InPost parcel machines, nor is it easily possible to connect it with BLIK type payments. For this reason, I am looking for someone who already has experience with such integrations and knows how to connect these add-ons to my site without affecting what I currently already have on the site - something I certainly don't want to lose.

Please let me know if you have already dealt with such projects. Additionally, I would like to point out, because I do not know if it makes any difference, that at the moment I do not have a business. I know that InPost requires such a business - what I want is to have a map with parcel machines on the website and for the customer to be able to choose any parcel machine from the map/possible list. The store is based on dropshipping, so I mainly need the ability to choose a parcel machine from the map, and not necessarily the integration of the entire system, because I will not be responsible for shipping packages.

For payments - here I want to use a separate payment gateway offering various methods including BLIK - integration with HotPay system.
