Academic Paper Checkover(Harvard but no sentence reconstruction)

My paper is 6800 words including references.

It needs to be fully checked for silly mistakes (spelling, typos, grammar).

I also want all the references checked for adherence to Harvard Reference style.

I do not need any sentences reconstructed for additional clarity (this has already been done). I just want to make sure there are no silly errors before submitting.

For someone familiar with Harvard Referencing this should take them no longer than 1-2 hours to complete.
