Discord Bot
I can make you a Discord bot!
I've made lots of Discord bots in the past. Currently I'm actively maintaining a bot called Goober Bot, which you can learn all about here. As of writing this, Goober Bot has 1,200+ installations!

With the details you provide, I can create a Discord bot perfectly tailored to your specification.
Q&A
Q: How complex can you go?
A: Pretty complex! I don't have an exact way to quantify it, but, if it gives you a decent idea, Goober Bot can play rock paper scissors.
Q: Can you use a 3rd-party API?
A: It depends. If it's free, then absolutely! If it's paid, you have to pay for it and provide the API key.
Q: How long will it take to make?
A: Again, it depends. For simple bots, it should take at most a week. For complex bots, it's more difficult to say, but probably within 1 or 2 months.
Q: How will I know how to set up the bot once it's done?
A: I will provide complete set up and maintenance instructions!
Q: What if something breaks in the future?
A: I can work on fixing things that break should that happen with no extra charge for up to a year after completing the commission.
Q: Will you host the bot?
A: No, I don't have the resources for that, but I'll do my best to help you find a hosting provider and I'll make it easy to self-host should that be the route you decide to go.
Q: Will you make graphical assets for the bot?
A: No, I'm not an artist, just a programmer. Sorry!
You'll get a custom Discord bot made to your specification.
