I can convert all of your videos quality up to 2K resolution (higher than Bluray) in 3 days (starting from Sunday) and the rest is uploading-downloading time, depends on the amount and size of your files.
I'm being honest here: if you want to convert videos below 480p quality to 1920*1080 HD, you will notice a bit of pixelated images (if someone says he/she could do it perfectly, he/she is definitely lying). Think as if you blew up a photo in photoshop from a very low resolution into a big banner. But if your videos are at 1020*720 resolution, I can even convert them to 2K with flawless quality.
Glad to hear from you soon :D
