Need bot to auto add new sign ups to specific channels

Hi Need a bot to auto add new signed up users to a specific set of channels especially since i just cant add thousands of people to one channel as for some reason there is a bug with that. As well I dont know anything about code just putting that out there but very much and humbly asking for assistance and yes i will pay for assistance with a bot that will auto add sign up users to a certain set of channels
I am not using the default channel feature for this cause i need people to be able to see some of the channels without sign up.

Email me if your interested: Katiestarling25@gmail.com thank you sooo much!
