hi, my name is Ngoc, im a 3d artist specialized in character design and modeling, i have read you project details and i really interested in it, as i really like to model character in real, And i would need some images on the face of that person, front view, left view, and i can do it from there. For a adult game, its fine with me, i have done several real person models before already. It still a hard work and time consuming, for me i will charge about 300 usd for one character, and it can be done within 4-5 days. I will keep the quality in the high standard, so you dont need to worry too much about this. Please contact me so we can discuss further, i also can share my previous models to you. Thanks and have a good day!
