Clothing brand needs several 3D shirts + change texture on the model

Hey. A large clothing brand needs 3D freelance for constant collaboration. You will need to make several styles of clothes once according to our patterns, then make a render for 20-30 different fabrics per season. The 3D model and photos do not need to be changed every season, only the material. In the attachment, I attach an example of photography and fabric. As a test task, I suggest drawing 3D or taking any ready-made 3D shirt and dressing it on a model with several fabric options, our fabric or any of your own, it does not matter, the main thing is to understand that you can do this, as well as waiting for payment at volumes of 20 styles of 20 fabrics.
If you have a lot of experience and high speed of work, ready to consider you for other goods, down jackets, dresses, etc.
Thank you.
