Comparison prices page for different stores

Need to create a comparison page that allows stores (Auto Parts and Services) have an inventory of their different articles and services, where thirds users can search for pieces from different stores using filters, comparing prices and distance where the store is located. Show images of products, Address, phone number this reinforces what the customer is buying.
(The filters and how the different inventories are updated is the most sensitive part)

It is a typical platform that contains a catalog of services that guide users according to what they are looking for.

Stores that are interested in selling their products on the platform must be registered, this registration must be approved by the platform administration,
and then stores can upload their inventories, photos and respective prices through an authorized user with ID and password.

(I posted this project before but have some trouble and the person who administered the requirements on this website retired so couldn’t develop it, now I am looking for someone who understands what I need and can develop it at a reasonable cost)
I have some example page and documents support, if you are interested show me your experience, works developed and strategy to use in our project. The team will be evaluating carefully your offer.
