keyless entrance system

I am looking to install a keyless entrance system that uses proximity as the main source of entry. This means using a key fob to gain access. The system will be used for both residential and commercial use. The installation of the system needs to be done very quickly - within four weeks. I need only parts of the code, like you can see in the schematic illustration. If you believe you would be a good fit for this project, please let me know. I am eager to get this keyless entrance system installed as soon as possible. Thank you!
