Build a cross-platform App (using react native, xamarin or you propose) with Firebase database

I am looking for a simple App where people can list their item for sale and chat (text, voice, video call) with the seller; similar to Carousell App (see link below).

[login to view URL]

[login to view URL]

In general, users can register as buyer or seller or both.

Sellers can list items for sale.

Buyers can search items for sale and filter based on country, category and price.

Buyers can contact sellers via text, voice or video chat.

Buyers can schedule the chat session (date and time) with the sellers.

Buyers can post a wish items (items that he want to buy) with price, sellers can accept the offer to complete the trade.

Payments will be made within the App using various payment method (e.g. visa, mastercard, paypal).

May I know the price and duration of completion (not urgent)?

I am on a low budget; however, I have the Network and Backing to potentially push the App to be as popular as FaceBook. If you are interested, I can offer a long-term partnership opportunities instead of a one time development fee.

The App must be secured and easy to maintain with clean source code. I will edit the source code in future since I have strong programming background.

I am based in Singapore. I am a game App developer who published multiple games App on Google and BlackBerry.
