You can rent a VPS for $5 per month and host multiple Masternodes on it (only if they are from different coins in most cases). There are various services in the $8-10 range that will manage your Masternode for you too, although I'm not sure which ones support SnowGem specifically.
In my opinion, investing into Masternode is very risky, mainly because real ROI will be much different than estimated ROI at the time investors decide to invest into their interest masternode coins.
I don't see how you can say that its very risky to invest into a Masternode. You can remove your funds at any time, there is no locked in contract or agreement and you always maintain control of your own collateral coins. You start receive payments within hours of setting up your Masternode. If you plan to hold coins for any period of time waiting for growth then Masternodes are just interest on your holdings.
