I like the combo idea... perhaps the Lunarpages Web Designer Package...
-Webhosting for Life... oh heck, dedicated server for life

-Web development software (CC makes sense, but since it is already included (at least on the shared plans) it should be something else I think to stand out)
-New desktop/laptop system with large widescreen (or both desktop & laptop)
-Certificates for on-line training courses related to improving web programming, graphic design, etc. skills (winner selects courses to match skill level/needs)
-few hundred dollars for use buying training materials (again, letting winner select to match skill level/needs)
- trip to LP HQ to claim the prize and be available for lots of photo ops
And to top it off, the winner gets Amy's salary for a year....

Okay, maybe that wouldn't be too exciting for people....
Oh, and allow for more than 1 winner... 1 grand prize, a few (say 4) 2nd prize (dedicated server and 2-3 of above), and a few (say 4) 3rd prize (dedicated and 1-2 of above, or scaled down versions/amount)... all with the dedicated hosting for life... then you can have headlines like LP to give away 10 Dedicated Hosting Plans free for Life!
VPS instead of dedicated might work as well... but the hosting should be something above the "basic" account... though with VPS & dedicated, there is the added issues of whether Plesk/cPanel is included with it, is the managed option included, etc.... but those are details that can be worked out later...
