I want to start a buy and sell marketplace on mobile platforms.
It will be similar to the "Citiboard" app.
Since there are no listings from the beginning I want to collect all buy/sell and auction sites on this platform like a search engine.
I want to be able to add any sites and apps myself.
I still want my users to upload their own listings.
The seller will be able to upload a listing with: Header, description, category, picture (s) / video, price, place and contact info.
More categories: sell, want to buy, pay to get rid of items, pay to get a service done, auctions,
