Proof reading documents

We are currently producing technical reports to commercial clients. We need a proofreader to read the reports and spot errors such as leaving placeholders in place. We would also need them to correct any obvious formatting errors. All documents are word, It is important that the work is turned around within 24 hours. We need the person to start ASAP. Must be UK based and native English speaker. There will be a lot of reports to read over the next couple of months.
