Frequency/Tone Generator -- 3

This project is do design hardware and programming that will run designated frequencies through speakers producing a corresponding audio tone in a specific sequence and then display the information on a LCD screen guiding a operator of the hardware to step through specific sequences and then automatically record the results into a memory device. If you can give me what you think is the approximate number of hours or cost to complete it would be helpful. Please place an initial bid but know that before accepting this project you will have the opportunity to review the full project and adjust your bid accordingly. I currently have some schematics, BOM files, and other work done in Altium I believe. The engineer I had working on this project has become ill and cannot continue with it. I prefer a Freelancer who can do the hardware, programming, and has a working relationship with a manufacturer for prototyping. I will require an NDA.
