I wouldn't recommend you buy this domain if you plan to develop it. Since there's already a VPS Hosting site at VPSHosting.com . The s at the end really devalued this name since people typing in will usually go to the VPShosting .com without the "s". You'll be losing traffic. There's just not any popular hosting companies using hostings in their brands since it's not correct spelling.
I would personally put a value of $100-$250 max on vpshostings.com
If it was VPShosts.com then the value could be at least 4 figures.
