telegram bot

i need one telegram bot for my channel. this need to be fully customizable for me: like, name of bot, username of bot ... so, what i need: one bot who send randon numbers between range. like raffle numbers example: i type: /raffle 1 200 i want bot sort one random number between 1 to 200 thats it another situation, if possible, i want this: when i type: /registeron 1 200 bot said: choose your number between 1 200 when one person type: /number 2 bot store name from that user in number 2 when another user type another /number 20 bot store name from user in number 20 if another user type one number was stored, bot said: number exists and send username stored in that number for checking purposes another function is: when i type: /listusers bot need to said all numbers from 1 200 and names stored in numbers like: 1-name 2-name 3- 4- 5-name if number dont have name, is because no one requested that number and be able to someone request. another function is: when all numbers is completed, bot said ALL NUMBERS IS COMPLETED RAFFLE START SOON and if someone request typing /number X bot said: no more spaces alowed. another function is: /eraseraffle - this function is when i want to create new raffle, so bot erase all names and numbers. and when i type /registeron 1 20 new raffle opens with numbers 1 to 20 ... thats it. obs. im able to raffle many times i want. example: im create one raffle with numbers between 1 20 i typed: /registeron 1 20 and when all users complete that numbers i type: /startraffle 5 i want bot type 5 random numbers between 1 20 .. like: raffle numbers between 1 to 20 numbers: 1 2 5 19 20 - 5 numbers in raffle or i want startraffle with 3 - so: /startraffle 3 understand? thats it. doubts just ask dont bid if you dont want to this job in my budged. i dont paid more than i request. i have another jobs to do. i preffer bot in js or nodejs... but up to you!
