seeking handyman referrals to address a dining room window issue

From an Eckington household:

I'm looking for a handyman. A large window in the dining room is falling down, I need someone to measure the window and cut two pieces of wood and insert them under the upper window sash so it will stay up. The window is current hanging by a thread, so I need someone quickly. Use of a small ladder is required, and I can supply that.
