Build a Magento e-Commerce site with API integration

I am looking for a skilled developer to install a Magento e-Commerce site with API integration.

The site should be similiar to this one:
https://www.hubside.store/fr/

It will be a website for selling smartphones AND subscriptions.
I need a functionning site but you don't need to add the actual products, only a couple of test products.

Products need to have several options in addition of the usual ones (color, condition...) :

1. choose credit option : ALMAPAY
a plugin exists: https://docs.almapay.com/docs/magento

2. Shipping : CHRONOPOST
a plugin exists https://www.chronopost.fr/sites/default/files/atoms/files/guide_magento_2.pdf

3. Payment: STRIPE
a plugin exists: https://stripe.com/docs/connectors/adobe-commerce/install

4. Subscriptions
API integration: https://developers.transatel.com/

5. Variable price
When a phone is bought with a subscription, the price changes
