That depends on a variety of factors, but I assume you're asking from the point of view of an ECU fan. If I'm correct, the low end teams of DI spend about 500k a year, though startup costs are pretty hefty, especially if you have to add a women's sport for Title IX. I don't know the exact figures of what Miami is funded, but I believe higher end schools spend a few million a year. Like it was posted on the other hockey thread going on now, Penn State got an $88 million donation from a married couple, which covered the costs of building a state-of-the-art arena and funding for the men's team, though not many schools have some random rich guy ready to do that (they own the Buffalo Sabres).
Miami had been nothing special for the most part until Enrico Blasi took over about a decade ago. Since then, we've been regular Frozen Four contenders (only NoDak has a longer NCAA tournament streak) and have even gotten a brand new ice arena (see link below for pictures). It cost $40 million but in addition to the main arena there's a recreational and practice rink too that's also used for synchronized skating.
I agree with the comments above. Hockey for us is a big revenue producer and really beefs up our athletic profile with football and basketball declining over the years. I suspect that some of that may have to do with hockey diverting a lot of funding and fan support from those sports, though there's no proof to back that up. SLU hockey may start up sometime in the near future, their anti-hockey president recently stepped down and they have plenty of arena options (on-campus arena could be retrofitted, Scottrade Center if not) for temporary usage. Other MAC schools like Buffalo would also be good fits as well.
My advice? It might not be meant to be unless you have some donors ready to write some checks for getting it off the ground. I don't know if you have a club team or even an arena available in Greenville, but it's difficult to start up a team, though you obviously know more about ECU athletics than I do. Alabama-Huntsville has been able to make hockey work in the south, perhaps you could too.
