I'd say your RLC prices are perfect for where you are now. As for your Gaia pricing I'd say START at 300m for a fullbody. To do this, I'd recommend auctions. The artshop forums pricing is laughable with the current inflation. Use monthly collectibles as a guide-line. If they're at 30m, that means 30m = $2.50
You charge $25 normally so 300m would be a fair price. Do auctions. Trust me.
