WooCommerce Styling & API

We have a NON Woocommerce theme and we need the Single Product/Account and Cart Pages styling changed so it fits within a grid and not full screen and links at the bottom removed.

Once that section is complete then we need to you link up from WooCommerce (Download product) an API from Highfields Training, so once the payment is taken (using Stripe) then client gets permission to then complete their e-learning training cost.

All API info will be supplied just need someone to link it all up with Stripe and Highfields e-learning system, Highfields have said it's an easy job as they supplied everything API keys/codes etc etc.
