Ani,
Its not a big expense. My memory is not as good as it should be, but I think the full contour survey with adjoining properties window hieghts etc etc cost only $1,500. If you just want a boundary survey it would be less than $1,000.
In fact, if I were on my old work computer I'd be able to attach the quote. If you need it then let me know and I'll get it off my computer at home. I also have the detailed requirement form that my architect provided which shows everything required of the surveyor. But for a subdivision, the detail required might be lower than that for my architect.
Cheers,
Michael.
