Fashion Design

I need either a program or a website built that will do the trick for which I am trying to do. I am a Marketing Co. who is working with fashion designers who design new & hip clothing for male & female. I need something simular to the program Poser 5 - My designers will design the clothing & before it is put into production I would like to have the drawings converted into digital files and the clothes applied to a vitual model where we would approve the design. We want to digitally design the clothes using virtual models. We use both PC & MAC - now this can be either software or a internet thing... meaning we go to www. ???? and make it password protected - and designers do their designs there - virtually and all and once we like it all - - we then send it all to production. Input - Suggestions & Ideas are appreciated. Thanks
