My team has about 130 jumps as of now. Our original plan was 200. We've got a pretty full schedule left before Nationals.
As far as team rates go, check around on dz web sites for an idea of what you can expect. The info listed above about SD AZ is easily accessible on their web site. SD Spaceland in Houston has a pretty neat team rate structure. Check it out at http://www.skydivespaceland.com/pricing/pricing_info_team.htm. SD Dallas has a similar setup, but with different rates.
This should give you an idea of what to expect.
If you want to get ever greater discounts, then you've got to start selling!
Generally the more involved a team is with a dz, the more the dz is willing to deviate from their "advertised rates" for the team (assuming they'll deviate at all!). The dz is a business... they're in this to make money. You've got to figure out how you can help them make money before they're willing to "spend" money on you.
