Photo to 3d model

I have a project to create four 3D models from a photo of two people, a dog, and a cat, for 3D printing to be used as game pieces. The dimensions for the 3D model will need to be determined by the freelancer based on the photo. The level of detail expected in the 3D model is moderate. The final model should be ready for 3D printing and have the necessary supports put into place. The outcome of this project should be a finished 3D model that is ready for 3D printing.
