NEED TO ADD MORE FEATURES TO MY PAGE. by Enny

HERE'S MY MAJOR PROJECT.

i'll like to add more features to my store page,currently we sell in wholesale but i'll like to add a Retail page on the same platform too. 
lets say when a customer goes in the website store page shows two division and option for the customer to choose if they intend buying in wholesale or Retails somewhere by the HEADER and this option MENU will be clickable. when the customer goes in the store,all they 1st see 1st is the  Retail page and there will be a menu which will say Wholesale(that menu will be located somewhere visible enough) also{2ND FEATURE} i want to make my store page social friendly enough,i'll like to always feature customer's picture on their birthday's and other customer's could write comments below the pictures which means i'l need to include DOB and DOB reminder alert/notification in the registration form. 

Thanks
