Copy write / proof read of investment pitch

Topic: Property investment pitch
Tone: Formal/Professional
Extensive research needed: no
Extra notes: Hello,

We are in the process of finishing an investment pitch looking to raise funds for property investment.

My wife and I are experienced property investors / developers and have had the pitch checked by investment angels and bankers; however, we now need an expert in proof reading to ensure there are no typing / spelling mistakes and that the grammar is correct.

There are 9-10 powerpoint slides and at a guess it would take 1 to 1.5 hours.

We are not looking for the content to be changed, only that there are no mistakes/errors and that it makes sense etc.

Thank you

David
