How to get new permanet nodes for alt coin

[cryptost]

Hi Guys,

I'm about to launch a new alt coin which i think the community will enjoy.

My question is what's the best way of getting nodes for the config file for launch so the network does not fall over, currently only have 2 of my machines as permanent nodes and I'm thinking that will not be enough for a launch? How many people do you need running the client before nodes in config are not needed?

Thanks
