Dear client, welcome to Freelancer community. I am a telecommunications and electronics engineer, I can do you system giving you an unique advantage: I have a simulator software to model your system and send you operational videos before any payment!!! I am experienced using Arduino and I2C LCD screens, you can see some sample projects using those components in my portfolio. I will model the schematic, program the system and show you operational videos with Arduino, buttons, sweep functionalities (forward, reverse, random, etc) and send you videos using LCD screen and buttons. Regarding TEA5767, I have no model for this component, but I have a library to drive it, this library allows to find stations, set frequency, get signal level, etc just by using simple instructions, this won't be a problem, I program this features here, you test it in your side and release payment after test.
Please, contact me in the chat to agree on specific terms (technical requirements, budget, deadline, etc). I can provide you sample pictures and videos about simulator.
I have a company based in Miami, FL. You can see some sample projects developed by us by reviewing our website at www.xbintech.com. We have experience developing this kind of jobs remotely.
Kindly regards
