Hi,
While I am interested in the project and I am confident that I can handle phase 1 of the project (as well as phase 2, but that needs to be further discussed and is not part of this bid), I would want to point out the following:
1. Do you have a VPS for the website or a hosting package that will give you a lot of hosting space ? Considering you want a file manager application, you should expect that hosting space will always be required.
2. What type of files do you want to allow people to upload on the website ? Generally it is not a good idea to allow for exe, bat etc. type of files to be uploaded directly on your server. I would advise on letting people upload all type of images, videos and archives (zip, rar), as the security for those can be checked.
3. Drag and Drop for file upload and management is only supported in the latest browsers on the market.
I look forward to hearing from you.
Regards,
Lucian
