Then you phrased your question badly - you don't need an image, but drivers for whatever your toy is. You do understand that "the image" contains the whole Windows OS, and "sharing" it would be against many EULA's, ToS's and forum rules. And yes - you get what you pay for. When I got my $85 Windows tablet made by great (by being unknown) company named XXXX, I was perfectly aware what I am getting, and how to manage it (starting with creating a recovery image).
I would start searching for drivers by Hardware IDs - PIDs and VIDs. You may also start looking at eStores for a tablet that looks similar to yours, but made by another great company named YYYY, and search for drivers on their website.
