is it possible to altered a jeans waist size?  I use to wear 32 now i'm wearing 29-30, if any tailor does the job, how much would it cost and where to get a good tailor to do it?

Hello people, I'm thinking of getting my jeans altered, at the waist because they've stretched out after some few washes. However, I don't want to go to those high end places that tailor suits for guys. Just some normal tailor will do. Any good recommendations around ? Living around Uptown Thanks !
