I am an experienced English writer, who would love to help you with your project. My strategy for the first round, would be to try and deliver draft versions of each page as quickly as possible, which we could then discuss, refine and edit, where need be.
I feel that I am a good choice, because I am English myself, meaning that I probably have a better innate understanding of the system than many of the writers on here. I also have nothing but five-star reviews and would look to bring the same high standards to your project. I am happy to provide samples of my previous work if you are interested and get in touch via the messaging system.
Please note that this bid is just for the first set, of 5 pages which from my reading of the description will be roughly 20,000-25,000 words. Happy to adjust downwards if I have misread or misunderstood the workload.
I personally prefer to work out in the mornings, though other options are just as valid.
