Тesting and comparing 5 open source API Gateways

As a software developer, I'm looking to hire someone to help me test and compare five open source API Gateways: Kong, Gloo, Ambasador, Tyk.io and Apache APISIX . This project is part of my thesis and the general goal of the project is to compare each other and which API Gateway best meets performance and scalability needs. Our requirements are not particularly high in terms of programming language or framework; however, we have a budget of less than $150 for this project. If you feel you have the technical knowledge to effectively evaluate and compare API Gateways and adhere to a tight budget, I'd love to hear from you.
