Replace the start with a button and solve some minor problem in Laravel "everything is working" -- 3

I am looking for an expert in Flutter and Laravel to make a modification to a taxi script, it works perfectly, the apps are published in Playstore but I need to modify the start to a simpler one that would be a button that fulfills a function and solve problems in Laravel that do not affect the operation of the App. It is too easy to solve for a person with good knowledge. I can pay up to USD 17 but it is not more than an hour of work.
