$10 a video huh? If you can find that on FIVER, go ahead but buyer beware. I edit, white balance and color match video (mostly my own and for the company I work for) but have done a couple commercial pieces. I charge $50/hour for editing and $75/hour for editing, WB and color match. I would shoot myself in the face if I only made $5 to edit a full dive video only to have someone who knows absolutely nothing about editing review my work and give me suggestions. But on FIVER, you are not getting divers to edit them which means you may not get the content you actually want.
Good luck and I look forward to seeing what you come up with.
