Kaylee Brown is a researcher, scholar, and paper helper. Writing a thesis paper is quite tricky. If you get someone who knows the path well, hire him. The co-supervisor can handle the thesis writing part. You can hire him as online paper help. You do not need to hire him full-time. Just ask him to go through the thesis paper and point out the scope for improvement. He will suggest how attractively you can write the thesis. The writing technique is also as important as the content of the paper. So, if required, ask for paper writing help from your co-supervisor too.
