Create a bot for discord

I'm looking for a talented freelancer to help me create a bot for my discord server. The language I would like the bot to be written in is Javascript. I don't have a source code for this, so I'm looking for someone to help me build it from scratch. The bot should have the functionality of adding a whitelist role based on a score from a google sheet. The bot should have an easy to use functionality and be able to quickly respond when needed. I'm looking for someone highly experienced in creating Discord bots and will be able to complete this project in a timely manner.
