See the change, be the change

So, I found a drywall dude. Not sure how good he'll be but the price was perfect and I don't have to do it. Huge blessing, and now I am just trying to get things ready for him. I can't believe how much the space will transform in the next month. Cabinets will be delivered on the 17th and if all goes well I'll have the flooring down before they arrive. That means in ~3weeks we'll have walls and floor. Although I know that it is going to seemingly shrink the space that has been massively open for the last several months, I'm glad I can finally see the progress.

So now I'm just finishing up the prep for the drywall which basically consists of putting in insulation, running the gas line for the range, and trimming out the sills for windows and hopefully installing the new window if it gets here in time.

One thing I need some help with.... I need to move the piano which has bunged up wheels. For those who have helped before, you know that I just have it sitting on moving dollies right now and unfortunately they aren't really effective. I would like to tip the piano over and lay it down so I can install new wheels on it and then of course get it back up and hopefully be able to roll it around. So, 2 questions:

1) Does anyone know if tipping the piano over will damage it?
2) Who can help us this weekend for about an hour while I do this? I'm thinking it will take 4 dudes, preferrably 5, including myself to get this thing tipped over and back up. It's very heavy. Feel free to post here if you are available. I'm open all weekend except for Sunday evening.

PS - if you have better suggestions, just let me know. Worst case scenario, I don't do the wheel installation and just move it over on a different wall.
