I want to sell our studio models, Please give me some advices. :)

Hi everybody,

Here is the thing, I have operated my own animation company for three years, we have 20 artists here, during the past time, we produced many projects relate to computer graphic, like 3D animation TV series, architectural presentation, CG advertising, game, and short film. I didn't mean to be a multi-industry media company, but we just had to working hard and eat anything come to me to feed ourselves, we are still living but in a hectic way. on the other hand, good thing is we found we accumulated lots of hi-quality 3D models.  most of them is architectural models, external and internal furniture and electric appliances, we also have animals, human, vehicles, medical equipments, etc. and we also have the copyright to sell some of them. 

This year our market has dropped a little, so I'm wondering if I can sell them on the internet.  but I never buy or sell models here.  my question is do you think selling models and textures will make a big benefit to our company? do you really earn money on this business? 

At the beginning, I panned to build my own website shop with logo and own domain to sell my hundreds of models and textures. but this will cost me hundreds dollars and three weeks to built it, may be $150 plus to maintain it per month. and also spend money on advertising it. benefit is I can have my own brand, if this works, I can expand this business, make and sell more models. 

or I can sell them here or other similar websites like turbosquid.com. but I have to face to many low price sellers. and also pay for the website. 

I believe the artists here are not only CG artists, you must have business sense, Please kindly give me some advices, what should I do now? is it worth for me to spend times and upload models on the net, or build my own website.  Thanks for telling me anything. I would like to hear your words. Thank you.

ps: I'm not a native english speaker, so pardon me if I make you confused :P  Thanks.
