I like 10k people will get butt hurt over it being too cheap but the low barrier of entry will work itself out when the market is snagging up SCORE for masternode's left and right especially with how cheap the price is now. I personally plan to host 4 nodes myself on a few PI's lying around. Just make the payout big enough for masternode holders and SCORE's value in the marketplace will be backed by the masternodes alone leaving you free to take the coin in whatever direction you feel like it needs to go to continue to make it even more valuable. Masternodes are just the beginning who cares if everyone has one thats good for the network less centralization is always a bonus the reward may go down but I'm willing to bet the price per SCORE will certainly go up.
Hopefully you have 4 Static IP's for these MN
I do actually no problem and they don't even cost me a thing so profit is just profit all the way to me; I could care less if the 12 year old can buy a masternode with his allowance let him it's a good investment better then the bs he would probably be wasting the money on otherwise. The more people purchase SCORE to get masternodes the more demand it will have and that's what coin needs to survive these days. Right now the price is cheap so snag them while you can because even 10k nodes will cost some BTC in the future.
