Just wanted to throw a little information in here:
You might find it difficult to submit to some of the larger tube sites as they may require you to pay for an uploader account where videos aren't rejected outright. I've read more than a few stories from fellow webmasters that have tried to use the larger tube sites to gain exposure for their site in the form of watermarked videos, and they were unable to get their videos approved without paying advertising rates. This may factor into how much you can pay your submitter if you choose to utilize the bigger tube sites.
Paying per video view may not be the best way to compensate your submitter because it's really quite easy to surreptitiously increase those video view numbers. Instead, you may want to consider compensating your submitter per video upload. This is something that is easily verified on your side and cheat-proof.
Having said that, there are numerous outsourcing companies with inexpensive labor that may be well-suited for your tasks. Make a post here asking for outsourcing companies to contact you, and I'm quite sure you'll be overwhelmed with responses.
Good luck!
