Google will likely raise a flag at any new site / url's of this size. Matt Cutts has been specific on this and suggested launching 5k of pages a week is the upper limit.

If [ as others say here ] you have plenty of "trust" you might be able to move faster. "Trust" means a site with an age of greater than say 18 months approx and plenty of backlinks. The older the site the more trust.

Then you need plenty of deep link juice well disbursed across your site. Otherwise, crawled pages given very low or nil PR will drag your overall site down the "plug hole" meaning storing them as supplemental pages. The effect is that you are given the appearance of never being indexed, because the page sit so low in the SERP's - maybe 950+ .

Why do you need 29.5 million pages? How many sites are there out there of this size, as an indication of the need?
