Try Allied Tube. Also, you can get dimensions of EMT from the McMaster Carr website or the Grainger Catalog website, and calculate your own section properties.
I frequently design miscellaneous struts from EMT as you are doing. I conservatively use 20 ksi allowable bending stress, but usually column buckling controls and the actual stress is much less.
I like the stuff because it is very ductile - it has to be so Sparky can bend all those offsets and such.

Does anyone know where I can find the structural properties for EMT tubing?
It is proposed for use as duct support and bracing.
Thanks,
