Looking for programmer/will pay

First post here, looking for someone who can write code for my Arduino. Not sure how much people charge, willing to pay. I have learned I hate learning/writing code but have great ideas for projects. This project I believe in theory as I’ve mapped out is simple but I have no idea where to begin with code.

Project is a home alarm system. Theory is, say 2 (or more) circuits when closed will allow a code to be entered. When code is entered if any of the 2 circuits becomes open it will trigger an alarm (siren). When code# is entered it will allow circuits to be open or closed without triggering alarm.
As an added fun idea since I have a GSM board if alarm is triggered then send text to # “alarm triggered”. You could reply "mute" (thus muting alarm(siren) and or text code# to turn off alarm completely.

Key pad could be bypassed completely or not needed if text setup would work.

So I believe in theory this is easy and I have the skills to build the setup in a home but very little knowledge of how to code this.

PM sent.
