Hi,
I can do this for you no worries, I am a structural designer in my real life, this gives me a bit of an edge as I can see any structural issues and deal with them before the design phase is over, this saves you time and money when you do get it engineered. The plan is straight forward, sections and details will not be a problem, my drawings will be to Australian standards, which will be to the same high standards of Canada, US, UK and Europe.
My fee will include any revisions, even after the building permit has been issued, I can also supply a proposed structural layout, this might be better done by someone local to you who will be more familiar with local materials and building methods.
If this suits you, feel free to contact me, I can start this in the next 24 hours.
Cheers,
Brett
