I agree with what has been said about sponsor content - we've all seen it (usually when a new set comes out, we get at least 10 submitters with the same content the next day)
The cost of buying content is pretty low - it wouldnt be a problem to find sets for $5-7 easily
Why make 2 sites per day when most of the LLs only take 1 a day? Take the site you make and make an AVS small site out of the same content and submit mirrors of it to AVS's that still accept submits - then take your two galleries on the free site - combine them and make a TGP gallery to submit to TGPs - and lastly, make a good SE free site out of your LL free site and submit it to DMOZ - that should keep you busy fo at least a few hours every day - then start putting together a hub ( a links page of all of your free sites) for the SE's.
Will you see 2 sales a day - sure thing - as long as you can write good sales text, make everything as clean as you can for the surfer and dont try to screw with them or the people you submit to - and after a hundred sites, you should be making at least 2 sales per day and a few extras from your SE listings and other streams of revenue
