Canon 20D or 30D & Battery Grip
Sigma 10-20 or Canon equivalent
Canon 24-105L IS USM
Canon 100-400L IS USM
Job done.
Or if you want a slightly different approach buy the
5D forget the battery grip and the Sigma/Canon wide lens.
For the Canon gear I would have no hesitation buying from the Canon outlet on ebay or using OneStop for any other items. You may even get some change from your budget if you buy at the right times
