Business or Home Designer/Architect need layout in digital format

Learning center concept that needs a mock up of the initial design. We will provide two hand drawn layouts that need to be converted into a model. Preferably 3d model if budget allows. Bidder needs to have experience with layouts because we need initial thoughts to pick which layout to be modeled. The design is basic and not detailed. If the initial design is approved then we will work on more detailed design. Cad experience a plus.
