Breathalyzer with RFID & Arduino UNO

I am looking for someone experienced in Arduino and RFID technologies to develop an Arduino UNO-powered breathalyzer project. Since I haven't yet decided if the breathalyzer will be for personal or commercial use, this could shape the route taken during development, and so flexibility will be key.

Key Features:
- The breathalyzer should be capable of detecting normal, alert, and high alcohol levels.
- It should integrate an RFID system for replicating car ignition - this needs to be programmed to work with any type of key fob.
- The alcohol levels should be displayed on a basic character LCD display.
- An optional feature would be a speaker that imitates car ignition sounds, depending on the availability of this module.

Ideal Skills and Experience:
- Proficient in Arduino and RFID technologies
- Practical expertise with LCD character displays
- Experience with developing breathalyzers is desirable
- Capacity to adapt to potential functional changes depending on usage of the project (personal vs commercial)

Please provide examples of similar projects you have completed in the past, if any. Looking forward to hearing from you!
