Even if you could get enough help from friends, you should not attempt to move the piano by yourselves. A piano can be very delicate when it comes to moving. Any crack or damage could already damage the quality of the sound it produces and such occurrence can largely lower the value the piano as well.
 
It does not mean though that you have to hire the most expensive removals company in the area. If you are with a tight budget, you can hire piano movers that consist of 2 men and a truck. As long as the people who will handle the piano have the ample experience in what they do, your piano would be in good hands.
 
Experience would have taught them the right techniques in lifting and navigating pianos through stairs, for instance. Of course, before you hire the piano movers, make sure that they also have the proper equipment for the job and they are properly insured as well.
 
To be sure that you will get the best deal though, make sure that you are clear about the fees. You should also be precise in giving the right size and weight of the piano and the right addresses of the locations. It would even be better if an ocular survey is done so you will get an accurate quote. But again, always go with good service if you want to make sure that your piano will be in good and safe hands.
