Hmm.. you know I never really bothered to think about what it would cost.   I suppose a 'real' coin launch should
at least be paying to keep running a web site,  a couple of seed nodes, dns seeds preferred.  Probably should have the later duplicate for a testnet.   May even want to have some testers.   If you don't know how to do any of the skills and have to hire it all out it probably does add up to more then one would think at first.
