I need to make my script / bot work with headless browsing!

Following my previous project(s), I currently have a script that auto adds to cart and auto check outs for purchasing items quickly, that eventually sell out instantly or within minutes. I am looking to get an even better advantage in the market by making my script faster, getting more product, etc. After doing some research and chatting with a handful of people, I think the best way to make my script FAST and getting an advantage over the average user or users that run a bot they bought in the market (mine is self made) is to run the script through headless browsing. I also run my script through a Chrome extension, so I think the headless browsing will allow us to directly add to cart and purchase items, without graphics, font, etc loading. From my understanding, headless browsing simply takes the website's code, rather than loading each graphic, button, font, etc. When the web page posts a new item, I believe there is a one minute period or so where code is readable (via script), then fully published for the average user. THIS IS THE CODE WE WANT TO READ AND ACTION ON. Because of the nature of the website my script is for, I use a proxy script with my add to cart / checkout script so each Chrome window is a unique IP address. This allows orders in each window to have a different IP which helps dilute my multiple purchases, which this website tries to avoid. Because I am not a CS major, some language I use, advantages and disadvantages of the script(s), may not be the best description, so please be understanding of this. I work in Finance, so computer language is not my first love! With that said, if anyone wants to take on a project to: 1. Convert / Mold my current Chrome script to a headless browsing script. 2. Ensure the new headless browsing script is compatible and functional with my proxy script. More smaller steps will be involved such as testing, perhaps on-going support for a few weeks while we use the script live, etc. If this project is successful, I have many other websites we can work on. Essentially, we can make a lot of money together. I am 100% serious with working this out in a reasonable time frame. I am prompt with communication and can pay a decent amount for your time and support. I am looking to complete this project ASAP. Thank you!!
