Send 1000k+ HTTP requests a second

We would essentially require a solution to make > 1000 HTTP requests in parallel a second. Our proxy provider allows us to use residential proxies with an incredibly low latency. Thus, speed is not a bottleneck in the given use-case nor should it be whatsoever. In terms of a programming language, we would prefer Golang or Python to be used. However, If you have anything else in mind then we're open to ideas! The plan would be to have a solution which makes > 1000 HTTP requests in parallel a second while connected to a specified HTTP proxy (Oxylabs). It is an absolute requirement that we meet these specifications and have the resources to do so. We have already looked into this topic but failed with little success due to host connection limitations or improper techniques used while attempting the given task. Thus, we have attempted to reach out to the world of Freelancer. The endpoint (i.e. [login to view URL]) in mind is not to change although the payload (data) sent shall change with each request. All required additional information shall be given upon request. If you think that you could assist us from a long-time perspective then please do let us know as there is an opportunity to make a fixed amount of $1000-2000 every week. See this as more-so a test of knowledge then anything. We have an example version of what we need done but it sadly has a bottleneck (hence why we posted here). P.S. This is an urgent listing so please get back to us if you think you can do the job!
