Form that upload files to Google Drive, with integration to Google Spreadsheets

I need a freelancer who can setup an html form where people can submit images and videoes. The files must be uploaded to MY Google Drive. Not the uploaders Google Drive. The uploader must be able to upload the file without signing in to his/hers Google Account. The uploaded files goes to folders in Google Drive according to a choosen checkbox on the website. In this project and my wireframe I will call them “tasks” The work will probably require understanding of the Google Drive API and the Google Spreadsheet API. Demands: The uploaded files must go to a folder in my Google Drive, that I decide. Could be: Google Drive-Root/Team 1/Folder-name-from-a-form-value Must support files up to 500 mb. The upload must be resumable Must have a progress bar that shows how much of the file has been uploaded during the upload. The form also needs integration to a Google Spreadsheet. The demands for this part: The form options/tasks must be controlled from the Google Spreadsheet. I need 100 tasks from the beginning but if I remove a task/mark a task solved in the spreadsheet, it will also disappear in the html form. And also if I add a new task during the day it will appear in the form. Everytime a file is uploaded to a specific task a link to the files public url is added to the spreadsheet. The concept: (See the attached wireframe) The uploader has a file on his phone. He goes to the website where he chooses the task/checkbox (at least one checkbox is mandatory) Then he pick the file he wants to upload (this is mandatory as well) When he clicks submit the file is uploaded to a folder with the same name as the task in my Google Drive. At the same time the task is marked solved in a Spreadsheet and a public url is posted in the spreadsheet as well. The textfields with the checkboxes can be controlled from the spreadsheet - new taks can be added and old tasks can be removed. Example: Task one is solved and I confirm it in the spreadsheet. Then it no longer appear on the list in the form. I have created a simple version of the html part that works. Just to give an understanding of the visible part of the system.
