This project will be a proposition of a potentially big project. If the project is accepted, scope will be extended meet client's requirements.
Note: This integration project will be developed as a functional prototype with pure php with no concern of user interface. Also it will be standalone and wont be embedded to Magento store admin [login to view URL] also, There wont be any user authentication or etc.
Note2: We have been using upwork extensively and spent more than 10K so far. As upwork limits the visibility of new standard project, we wanted to open it here to meet new potentials.
