How big can they grow?

I've been looking and researching this one, looks interesting.

NSR has 33% of the market, and almost 10% of the revenues in the market (NSR rev 79.8 million, industry is worth 752 million at this time apparently, projected to grow to 808 million by 2020). Industry is growing at 3.3% per year. With over 600 players in the same, it seems they're gonna need to keep buying other players to keep the growth going.

Another interesting thing I came across - there are some startups who have a product whereby they ship containers to your home, you pack em, they pick em up for you and store it, avoids the hassle of having to drive the stuff to the warehouse yourself. Interestingly, a UK mob by the name of Spaceways tried it here but packed up and bailed on the Aus market within 6 months, but there are a few others like Boxly and Boxbird - an interesting idea that perhaps NSR could adopt if there is a demand for it, any thoughts?
