Desktop Windows Application (Uploader)

I need a developer to write a windows desktop application, it will be shared as freeware. The point of the program is to upload via a desktop application images ( jpg, png, etc. ) to an PHP Api installed on a webserver, and deliver to the user the link(s) of the uploaded image(s). The PHP script is simple : the user send a post data (multipart/form-data) and it returns the link that the program have to fetch. The features : `#1 : GUI designed by photoshop will be provided by us, and have to be coded. #2 : Upload multiple files at the same time, progress bar. the user can cancel the upload. #3 : List all the selected files and enable the user to manage ( add/remove/clear ) them, before uploading. #4 : Save as history the uploaded files. #5 : Multilanguage support ( I'll provide french translation) #6 : Windows implantation : when the user does a right click, there is a element in "Send to" named (in english version) "Send to NoelShack" ( NoelShack is the name of the application) and then it will launch nOelShack. #7 : When NoelShack is launched (or hidden in taskbar) there is an option "Hook Print Screen Button", if it's checked, then when the user presses the Print Scr. button the desktop of the user will be screened, an notification (sound) will be launched, after the user could launch the upload of the screened images. Budget : $50.
