You’d be better off learning it yourself, step-by-step. Read all the docs for automations here and also take a look at some examples. Try some simple things first, like turning on a light when there is motion and if you get stuck and consulted the docs and are still stuck, come here for help, post your code that is not working and what you want it to do. Please also read the community guidelines here.
If you pay someone to do it, you’ll be lost again when there is a breaking change during an update or similar things.
