I've worked on numerous Optical Character Recognition (OCR) projects like this and Captcha solving projects using Tesseract, PyTorch and Tensorflow using the state-of-the-art Artificial Neural Networks, Deep Learning and Artificial Intelligence methods.
I've read the description and inspected the data you have sent. I can do it in just several hours for a really modest price. You can send me the data and after I send you my results, you can award me the project. Since the data you sent is really easy to recognize, I'm pretty sure I can have more than 95% accuracy on this one.
A small note: Even if you don't choose me, don't ever spend more than 75$ for this project since if your dataset is like this, I think this is a really easy project.
