Move Large Sofa Upstairs

I need experienced movers to carry a large, heavy sofa from the ground floor to the second floor of my home. The only access is an L-shaped staircase with a landing in the middle; there are no low ceilings, tight corners, or other obstructions to worry about. Because I’ll be on site alone, you’ll need to supply all the muscle, equipment, and protective gear (straps, blankets, corner guards, etc.) to keep both the sofa and the walls scuff-free.

I also want an armchair bought downstairs

Please let me know:
• How many movers you will bring
• The equipment you plan to use
• Your estimated time to complete the job and preferred schedule

Payment will be released once the sofa is safely positioned upstairs without damage.
