Give a brief reply to this:
"Good morning, Hope this meets you well. I humbly wish to ask for a deadline extension/modification of contract to the 14th of August, 2023. I also wish to be given free space to work on this project without giving you updates until the end of the day on 10th of August, 2023. This would give me the much needed time and space without pressure to deliver on this project putting in my utmost best; and if possible, I would go the extra mile after this to ensuring that this project attains the exact standard you would love it to, until you are more than 100% satisfied with the results. I would have said, "Trust me on this", but I understand you may find it difficult to. But I implore you to give me the benefit of the doubt. This would never repeat itself on this / future projects with you. You can hold me on this promise, if in the future, I happen to go against this. Sorry for the inconvenience "this adjustment must have definitely caused you" and I hope to make up for this. Hoping that you consider this. Wish you a wonderful day."
