I honestly hope you did not expect an anser. 
The GOLDEN years are over.

Some might make some, but most slutwear has been build, and build over and all over again.

Renders??? There are thousands out there that sell something once in while. 

Building a reputation is the hard part, and Poser or DS are just tools in your toolbox.
Poser or DS are a hobby. Have fun.

Wanna make money?
Find a Job.
Wanna have some learning fun?
Play with 3D.

Wanna make content? Great.
Start with free items here, show the quality you can deliver.

Build a reputation.

Then and only then, you can start selling. (and hopefully make some pocket money)

Those that HAVE a reputation and KNOW the anser will not come here and give it to you on a gold plate.
