My suggestion is that you write it yourself. I've been there before, and I finished my graduation thesis myself. From design to operation to paper submission, every process is basically learned by practice. It is also for this reason that I was hired by the relevant enterprises involved in the thesis as soon as I graduated. So I think no matter how tight the time is, it is absolutely good for you to write it yourself. I don't think it is original. In addition, if more people use it, they may repeat it with others.
