Customize, add section and test a php/ Laravel e Wallet Script for launching. -- 2

I need the services of an experienced, meticulous and expert full stack developer with above average knowledge and expertise in php/ laravel e wallet system to update source code, fix any bugs, customize, add section and test a pre deployed php/ Laravel Wallet Script and get ready for launching. The Script has been deployed and a lot of work has been done on it so I will be expecting a completion time of 3 days. The person will be required to handle all aspect that is needed to complete the project and get the pre deployed script ready for launching and previous knowledge, understanding, experience and expertise of working on similar payment services project is required. This might result in a long term working arrangement depending on the outcome. NB: Please don't bid on this project if you think the price is low or if you plan on charging extra. Thank you.
