I am going to open a new microstock website.
Another new one? Sigh. After Snapvillage, Geckostock, PhotoStorage, Newdarkroom? It must be the season.
The only new ones that sortof made it in the low top 10 are Featurepics and LuckyOliver. They had an innovative concept. LO is strong in community building, FP is strong in setting your own prices and high % payout. Both were designed well from the start with all features present, unlike Snapvillage.
In this oversaturated market, what's going to be your USP? It was easy for ShutterStock to gain ground in a very profitable subscription market because it was the first. The market has been taken 100% now, so your USP should be very good. Anyone (including me) can program a stock site. Marketing makes the difference.
Oh, and don't even count on having any lift-off before you have more than 300,000 photos online. I hope you have very deep pockets to bridge those 2-3 years without any income. ;-)
Just a thought. Reviewers get paid 0.1$ per image reviewed. That means 3,000$. Support, forums, sales... one full-time worker at least. 30,000$ per year.
Good luck ;-)
