If you want fast and guaranteed crawling, create a google adsense account and ad the google ad to the source code of your site. You can do this just until they spider the site, and you can probably do it on pages that simply link to your important content, and which only spiders are otherwise going to be likely to find. Since they advertise based on content, they'll have to spider your site, discover it's existence, index it, and presumably index all of the pages that you actually -want- it to see as well.
Then remove the ads whenever you're ready.
