need 3d bust model

I am in need of a 3D character bust model. I have some specific proportions in mind, so that needs to be considered during the development process. The desired output format is .stl. I plan on using the model for commercial purposes, and it will need to be high-quality and accurate. I'm looking for an experienced 3D artist who can meet my expectations, and produce the model in a timely manner. If you believe you have the skills and experience to handle this project, please contact me. I look forward to working with you.
