Improvements on the site. Creating LC wholesale and retail, paying on the site, button favorites. (MODX system)

I salute everyone!
We need to refine the site myverushka.com
Create a personal office for retail and wholesale buyers, which will reflect selected goods, the history of orders, as well as for wholesale buyers will be visible wholesale prices.
You also need to add payment to the site
The site is developed on the MODX system, hosting Beget.
