Every Dry Cleaner in my city seems to have a tailor/ seamstress.
I get my dress shirts laundered and ironed for $1 each.
The occasional button or fix it they do for free for me.
A pant hem would be cheap.

Or go to the local fabric store, they will surly know someone who can do it, or I'll put $ on it that one of the employees will do you a lil favor.

Who knows you may meet a friend with benefits . Sewing benefits that is.

Either one of these will allow you to buy off the shelf stuff and made to fit you for next to nothing extra.
