Hello!
Well, I'll start with the traditional: "my experience is great, I read the assignment carefully, blah blah blah ..."
In essence.
I have several ready-made projects like yours, and I can complete your project with high quality. Please note that this will not be a compilation of pieces of code from the Internet. This will be a "holistic" project designed specifically for you.
It will be both software and a printed circuit board for your device, designed taking into account the requirements of the manufacturer ESP8266 and oriented for low power consumption.
Freelance is my main income, so I work six days a week for 8 hours.
