Data entry - manufacturer and model names

About this project

Willing to pay for this to be prioritized and willing to pay more for faster completion! If you would rather ask for more details and bid on this as a fixed-price project, I am open to that, but I do not know how long it might take and want to be fair on pricing. I want to build a list of all possible Manufacturers and Models that can be listed for sale on a website. They only display 9 options at a time. The process I am looking for help with is: 1. Pick a category from their list 2. Find all possible manufacturers that produce options in that Category: start by typing the letter "A" into the Manufacturer search bar and proceeding through the letter "Z" then trying the numbers 0-9 for Manufacturer, and, any time there are 9 or more options, add the letters A-Z and 0-9 on to the end of whatever letters are currently there (at times, with more common strings you might have to go several letters and numbers deep) until you have a list with fewer than 9 entries 3. For each Manufacturer, repeat the same search procedure (A-Z, 0-9, etc.) to list all Models within that aircraft category The desired end result is a Google Sheet where column A is the Model, B is the Manufacturer, and C is the Category that forms a complete list of all possible Manufacturers and Models. Expecting around 5,000-10,000 rows of data. I do not know if this can be automated or will need to be done manually. Very open to different processes as well, as long as they offer a complete list.
