Custom woocommerce plugin

I have a php/mysql "visual plan maker" where customers can customise a product in real time, the goal is to integrate this into a woocommerce webshop and be able to add the custom products to the woocommerce cart. Stock management not required atm. The actual code must be reviewed and if necessarily, replaced based on best practice and security measures to maximize customer expreience and avoid any security issues.

The values must be carried as labels to the checkout to be visible both to the customers and the staff who processing the order (making the customised product):

- product colour
- design
- design colour
- product width (2-3 size)
- generated thumbnail

The product price is based only the width value at the moment.
eg.
6cm width - price 1
7cm width - price 2
8cm width - price 3

Any questions feel free to contact me.
Looking forward to find a developer with high standards who we can keep busy in a long run with additional projects.
