Hi Roland - this is just MY opinion, but if you have good ideas for some products, go straight to selling. Giving away freebies is not always an accurate way to 'test the market'.  Just go for it! You may be surprised by the results :)   For vendors, freebies should be more of a tool to promote their products and not necessarily build a following - do you want a following of freebie downloaders, or do you want paying customers?

Good luck with whatever you decide to do! People here at Rendo are always ready to lend a hand - that's what makes this community so great :)

Cheers :)
