The install fee is only applicable should you not want to install the forum by yourself, it's not that difficult. An alternative would be to hire a 'dev guy (such as me, allen ayres, etc) to install it for you as well.
As for the turnaround, I'm unsure with groupee's side of things, I believe it'd likely be a couple of days to roll it out.
As for your current data, I'd love to see if you're running the only supporter forum we allow imports from (phpbb) however I don't read chinese and thus cannot decypher your site...
