Any good trek/tour companies for Macchu Picchu? - trekking companies

I am in Cusco, Peru for a few weeks this summer as a volunteer in an orphanage. I have the weekend, and I told myself that I can take a 2-4 day hike to Machu Picchu. Any reccomendations for companies that respond to this? (I'm young and traveling alone in order to be with a group would be great) other travel advice to see / things would be much appreciated!
