Hi.  If any of your trees are a bit overgrown and could use a light trim to prevent them from brushing against your/your neighbor's house, you might want to contact 
Joshua Hill,  a recent transplant to Pgh. who knows how/where to trim trees and does this as a side business.  Joshua just trimmed a tree on my next-door neighbor's property that was brushing against my house and did a great job.
