I have a background in language and literacy education and hold professional qualifications in proofreading and copy editing. I work as a marker of national writing tests and regularly proof read school reports. I love working with English and am pedantic about its correctness. My skills in all areas of English, including both UK/Australian and US spelling and punctuation, are excellent (I consistently score in the top few percent in any tests).
I have worked on a wide variety of projects, including websites. The one that sounds most like your project, however, was when I wrote summaries and sets of course descriptions for a teachers' professional development site. If there is a lot of writing and researching to be done on your project, however, I feel it necessary to point out that your budget is low.
Here are a couple of feedback comments on recent projects I have worked on:
• I had a look on your corrections and was impressed by the quality and preciseness of your work
• Wow, you have done a great job. Thank you for all your work and so fast. We really liked the work you have completed and will keep you in mind for future projects.
I can complete a sample of your text as a test, if you wish.
