Hi Drifterlee

I agree with everyone here about the Poser market.  The only thing I will add is don't limit yourself,  consider all the markets.  In the cg world there are 3 categories to the markets;  high end,  mid range,  and low end.  High end;  movies,  television, and video games.  Mid range;  medical, litigation, law enforcement, real estate, architects, engineers, and interior designers.  Low end;  brokerages. 

Each are important and each serve a purpose.  The most important aspect of the low end market is exposure.  So, you may want to consider the Sims and Second Life as well as Poser and Daz Studio.  Mid range is the biggest market and where you will make the most money.  I would suggest while you are creating your content for the Low end market,  start collecting names and addresses of potential clients in the Mid range market.  High end market, top paying but it is also the smallest market of the three.

BTW,  the going rate for mid range is $50.00 an hour multiplied by 1.5 to 2 for profit.  It's a big world out there and so few of us doing this,  don't undersell yourself when bidding work.

I hope this helps

Cheers
