Hi, my name is Zane from Queensland SEO, based in Australia.
The project sounds simple enough however do you have some examples of the page style or some of the content so we can get an idea and confirm the 4-5hr project duration.
If we can get started within the next 48hrs, I would look at completing your project by the end of the week at the latest (24th of April).
We would obviously require FTP access however we can discuss that if and when the time comes.
Thank you and have a nice day,
Zane
