Some Improvments

Good evening,
I'm looking for someone who can help me with the evolution of my site:
1 - there are functions to restart: this concerns the display of prices, with and without VAT, in Euro or according to the chosen currency
2- there are changes to be made on the presentation of the product (HTML tabs), and the expression of the price per unit of sale.
I'm looking for someone who knows these issues.
See the attached specifications and tell me if it seems feasible to you quickly.
Thank you
