Inquiry about Custom Electronic Throttle Controller for Tesla Model 3/Y

I am looking for a supplier who can custom develop an electronic throttle controller / pedal booster for Tesla vehicles, specifically Model 3 and Model Y. I need to know if you have or can develop a version compatible with Tesla's accelerator pedal connector and voltage signal range, including dual-channel signal handling. I also need information on the process, cost, timeline for a small initial batch (10-50 units) and larger volume pricing, as well as whether units can be supplied without branding. Please provide details on certifications and minimum order quantity for a custom sample.
