How much should i pay for a custom video editing bot for youtube ?

Hey i found a programmer who will make me a custom script that will take videos in a folder , edit them together , add effect and transition , add voice , add music and then automatically upload it to youtube.

I've seen him talking about premium prices

Anyone already purchased something like this can tell me how much it actually costs ?
is there known price ranges ? how much do you think my bot should cost ?
