Looking for someone to fix some issues on my website/backend with a Larivell custom system

I had fixed a few things in the past and code got reverted. I have some drop-downs in my backend that need to go to correct place. Need to fix invoice system. All is already built, just need someone is can fix things fast and is available. Need someone who is proficient in Larivell. Need to speak english as it's too complicated for me personally to explain in text. The tasks were all fixed previously but got reverted when an issue happened.
