Zidane you said you are getting a job and willing to spend so here is some stuff you might want to invest in early before the community grows too big:
- A domain name (.com .net .info ect.)
- A host (EX: Godaddy.com)
- Choose your BB Software
- Set up a website (Homepage ect.)
- Other stuff you can think of you might need.
Just somethings you will want to look into if you want to become a big community like RuneLocus or something.
