I need someone to help me finish building my MLM & p gateway

I seek an experienced web developer to integrate my multi-level marketing platform with a payment processing system using Laravel language. The development of this site is underway but integration of the membership and compensation modules with a gateway is proving challenging. A variety of errors have surfaced during attempted implementations, halting progress. Solid knowledge of PHP, payment APIs, and e-commerce workflows is required to resolve integration issues, ensure security and functionality. Payment and user data must be handled according to best practices. The work pertains to linking customized membership and compensation management systems to a gateway to process member signups and transactions. The task requires expertise and must be completed within two business days. Qualified applicants should demonstrate proficiency integrating complex systems within tight deadlines.
