There is no hourly limit in terms of hours they say you need, what you will come up against is the minimum hourly required by his insurance company. I can tell you from my own recent experience that if he allows anyone with less than 500 hours to fly his aircraft the premiums will most likely be twice as expensive, and depending on the aircraft type that could be up to 10,000 in the difference
per plane.
As mentioned above networking is more important than the hours, I got the chance at my dropzone despite having under the minimums because I made an effort to fit in and get to know people, now I'm above the minimums and I don't have to fit in anymore!

ha! sucks for them!
In all seriousness best of luck if you manage it but flying skydivers is not as easy as you may think, its lots of fun, the money sucks, the beer is frequent but the responsibilities are real. You will most likely deal with real weather for the first time. Also you have to make critical decisions in terms of 'should I go/stay'' or 'will I wait for a clearance or will I return to land with a full load on a now wet, short, grass runway with bad weather in borderline crosswinds'.
Go for it if you can, its a piece of cake in great weather, lucky we get such awesome summers in Northern Europe.....
