The Online Service Marketplace application aims to act as a 
marketplace(Ex. Airtasker.com) to hire help by customers for their local 
needs. This application would have the ability to post tasks, bid offers 
and make Escrow payments using payment gateway.

Platforms - Web, Android and iOS.

At a very preliminary stage:

1) I would like to understand the costing budget to develop one model as 
mentioned above.
2) The platform must have no restrictions to be able to handle any 
number of traffic users.
3) We prefer Hybrid, so send cost and timeline for this. if can please provide estimation for Native development too.
