Architectural visualization (3DS Max) - dozens of projects

Hello, I have a lot of 3d visualization job to outsource to freelancers. I will provide AutoCAD drawings (2D) and a brief description on what needs to be done. Most of the times we need a few (2-3) renderings of both interiors and exteriors. Please indicate your average cost per rendering when bidding. There are a lot of project on the way. Thank you.
