Need to proofread ~7100 words in British English

I'm looking for an experienced proofreader who is fluent in British English to edit 5 articles of 1000-1500 words each, ~7100 words total.

I have 4 articles right now, the 5th should be ready on Friday. Topics: places to visit in London.

Also, I need your honest feedback on which articles are good or bad in terms of grammar, attention to detail (research), and ease of read. Something like this: "Articles #1 and #5 were mediocre. #2 was the worst one. #3 and #4 were by far the best-written articles."

Thank you
