Design a circuit for an ultrasonic distance sensor

We are looking for someone to assist with designing an ultrasonic distance measuring circuit. The design is to be operable between 2.7 and 3.3V and must communicate with a microcontroller using a serial digital interface. We are looking for something similar to the HC-SR04 and similar modules readily available online, however we have requirements that do not allow us to use these off-the-shelf modules.

Please reply with your relevant experience or qualifications, so we can contact you to discuss further details. Thanks.

Skills: Circuit Design, Electrical Engineering, Electronics, Microcontroller, PCB Layout
