Video editing, stabilizing, color correction, sound edit

I have hours of video material that needs stabilizing, color correction and sound fixing (improve voice etc.) Tools: Final Cut pro/express Example 1: I send you a videofile (dropbox) that needs to be stabilized motion. You send the file back (same video-format) stabilized. Example 2: I send you a videofile + final cut pro project file that needs color correction. You edit the project file in the dropbox. I check if OK. If i have comment - I write to you. You change upon my request. Example 3: I send you a videofile + final cut pro project file that needs to have the sound improved (remove hum, improve voice etc.) You send back in my dropbox. If i have comment - I write to you. You change upon my request.
