Hi,
I would like to do this project for you. I have a couple of questions, which will help me ensure that I've quoted you the right price, as well as assure you that I have, in fact, read your project brief.
1) I'm assuming that the file to be uploaded will be selected through the standard file submission dialog or through a drag-drop action. Is this correct? (The other alternative would be uploading a predetermined file, which would add complexity. This is an unlikely feature request, but I need to make sure.)
2) I would like to see some specification of the API. It doesn't need to be anything formal, just the sequence of HTTP requests that need to happen in order for file to be uploaded. In particular I'm interested in your method of authentication.
I'm looking forward to working with you,
Calin B.
