Hey r/DIY, I bought a single 4 x 3 foot magnetic chalkboard with an aluminum frame. I quickly realized it’s quite a hassle having to bend down or go on my knees to write in the lower areas, so I’m looking for some kind of unit to install that allows me to slide my chalkboard vertically. What and where would I need to shop to have everything I need? And how much would it cost me, if you had to guess within the ballpark? Any help would be greatly appreciated.

Here is the chalkboard in question:
