Hi and welcome to yorkie talk!
I have a very similar situation as you. I live on the 3rd floor of an apartment, and running up and down all those stairs got old really fast. So we built our own little thing like that. We just made a little box and planned on buying some sod and just replacing the sod every 2 weeks or so. Well, this was at the end of November, and sod was out of season then. So we ended up putting pee pads in it. That way he's at least getting used to going outside.
So maybe think about making your own little "balcony park" instead of spending all that money.
Good luck!
