3D illustration maker

I am looking for someone to create 3D illustrations for me. Specifically, I require an illustration of architecture, with reference images and a level of detail that is detailed. I have reference images and ideas for the illustration, but I am open to any creative input and suggestions. I need someone with experience in 3D illustration and with excellent attention to detail that will not leave out any small details. The project must be completed in a timely manner and up to the highest standard.
