My name is Jasimma & I am an interior Architect working in Sydney Australia. I have been a designer for 10 years and have been working on my own for the past 5 years.
I don't usually work in the imperial system, however seeing as your architect will be sending through mark-up of existing drawings, I don't think there will be any issues.
Last year I worked on a restaurant in Florida, Orlando & was able to work with the conversion of metric to imperial, easily.

I would be more than happy to email through my resume, if you could provide your contact details. Regarding fees, my usual hourly rate is $80 AUD per hour, however I would be happy to provide an estimate or work from a fixed fee if you would like to send through the work needed to be done, so I can see how long I feel it would take me to complete. Also happy to discuss your budget and go from there.
Please feel free to send through any further questions.
I look forward to hearing from you.
