Archive Gmail attachment to DropBox and return its share Link

It is only one hour job in order for you to demonstrate to me that you know how to call DropBox API from Google App via Google Javascript. The Script will upload email attachment from Gmail to DropBox folder and will return it's link. All you have to supply is a Google spreadsheet with this simple script source code. (All user data such as Gmail labels, DropBox folder, "App key" ,"App secret" can be hardcode). It is very simple script that an expert can do it in 1 hour (If you didnt done such calls from Google App to External API at the past it not for you). It is a way for me to know if you as a programmer is an expert for future jobs. I have done it by myself and it took me less than 1 hour to complete the all task. I want to have a short list of experts that will be ready to do future jobs for me. If you cant do it in less than 1 hour please say NO and I will look for another expert. Can you do it in 1 hour (10$)?
