Hello Jamie
With a 98% pass for top level 3 US English and being a full-time editor and proofreader, I would be very happy to help you with all your proofreading and editing.
I have placed a basic bid as you say it is a very simple 10 minute project and I have some spare time this morning.
I know it may be extra trouble for you, but Freelancer love these small fixed-price projects as they have a minimum fee of $3.00, which is 30% of my bid - yet they encourage you to become a premium member so you only pay 3% fees. It's a bit of a rip-off, however if you are able to repost this project without incurring a cancellation fee yourself, and repost it an an hourly rate project, I would be happy to place another bid at $10.00/ hour as Freelancer take only 3% from hourly projects. It's a daft system!
Hopefully both feedback and ratings for proofreading projects will assure you of swift and professional work at all times.
Kind Regards
David
