Additions to website [Prestashop]

Hello, I have a cafe webpage where some changes need to be done. 1- The first thing is that there are 40 ingridients for the pizzas, so a person can add them to standart pizzas if he wishes for additional price. The price varies depending on pizza size (for Mittel - 0.80 Euro, Gross - 1.00 Euro, Family - 2.00 Euro, Party - 3.00 Euro). If you go to this link [login to view URL] you can see that it is implemented. Just need to populate it for all pizzas and pizza variations. 2- There are 4 types of menus (so called combos). This is not implemented at all, even the products are not in the system. Can be hardcoded somehow, since there will not be any other type of menus. - Single Pizza for 9.90 Euro: This is a 28cm size pizza which is selected from pizza types and with 3 additional ingridients for free, a salad and a drink (0.33l). The person should be able to select all those features and they should appear in the invoice. So he is able to select 3 ingridients for free (if he selects 4, then 3 for free and the 4th will cost 0.80 Euro). Then he should be able to select the salat sause and the soft drink. There also a comment field needed, which will appear in invoice. - Grosse Pizza for 11.90 Euro: This is a 32cm size pizza which is selected from pizza types and with 3 additional ingridients for free, a salad and a drink (0.33l). The person should be able to select all those features and they should appear in the invoice. So he is able to select 3 ingridients for free (if he selects 4, then 3 for free and the 4th will cost 1.00 Euro). Then he should be able to select the salat sause and the soft drink. There also a comment field needed, which will appear in invoice. - Family Pizza for 20.90 Euro: This is a 45*32cm size pizza which is selected from pizza types and with 3 additional ingridients for free and a drink (1.00 l). The person should be able to select all those features and they should appear in the invoice. So he is able to select 3 ingridients for free (if he selects 4, then 3 for free and the 4th will cost 2.00 Euro). Then he should be able to select the soft drink. There also a comment field needed, which will appear in invoice. - Party Pizza for 24.50 Euro: This is a 60*40cm size pizza which is selected from pizza types and with 3 additional ingridients for free and 2 drinks (1.00 l). The person should be able to select all those features and they should appear in the invoice. So he is able to select 3 ingridients for free (if he selects 4, then 3 for free and the 4th will cost 3.00 Euro). Then he should be able to select the soft drinks (2 of them). There also a comment field needed, which will appear in invoice. P.S.: Due to an advice, we bought the current module - [login to view URL] and tried to work with it, but no chance. Need some help on this issue.
