I have been doing submissions for people online for a few years now. In Jan 2010 I put up a small site for people to order online, so far it has been very successful. about $50 to $100 a month in sales which is all profit. (this is lowest, so far this month has been over 200$)
The site is MillionSubmissions.com
It is nothing special, when orders are made they make payment, then get forwarded to a form that they can put in their site info. Then that gets sent to me and I do the submissions within 72 hours, The software I use generates a report and I upload it to a report directory on the url.

Total work doing the submissions monthly is about 3 hours.
New owner will get the software I use with LEGAL license and instructions on how to do submissions, also will get all my contacts for submissions done in the past, they will receive domain, site, and Hosting for a few months if needed.

All profits can be verifed to interested parties with paypal screenshots.
Shoot me any offers.
thanks
