Does the theme has following functions: 


1) Bulk products import option i.e. CVS or an excel file?

2) A "Wanted"or "Buy Requirement" option for potential buyers to list or upload pictures of a product they are looking for to purchase? 

3) What are the image pixel guideline to upload products?  Is it flexible? 

4) Can seller and interested buyer communicate directly? 


Appreciate your quick reply
