Due to the some issues that arises with goods like this regarding measurements and details, I prefer offline shopping. I have ordered for some specific sizes and only to get wrong measurements. Offline shopping is my recommendation.
When it comes to looking for business locally, I would recommend yellow pages or google business listings. There are maps and phone numbers. You can narrow down the nearest store.
I don't think selling them would be worth anything, unless you've got a sack of them. Price depends on the kilo, so it does not matter the quality of your suits.
