Proofread Dissertaion - British English

I hope you are doing good! I'll be finishing my dissertation on Saturday at around 6:00 pm, and I would like a native British speaker to double-check it and find any errors until Monday 3:00 pm BST. The length of the dissertation is around 45 pages. I can provide approx. 15 pages to be reviewed on Friday before 6:00 pm and the rest of the pages will be delivered on Saturday at around 6:00 pm.

Do you think you can do it? If yes, could you please let me know the cost? I know the time period is short, so if you don't have the capacity to do the project, there is no problem.

Thanks so much!
