When I applied under a business name, it took about 3 weeks for Apple to finally contact me asking for business documents. In the interim, I applied as an individual and I was approved immediately.

I finally got first app approved and onto the app store this week. When I first submit, I was rejected exactly 7 days after submission. I fixed my error (wrong version in the Info.plist file) and resubmit the same day I received the rejection email. 5 days after the resubmission my app was approved for sale.

Once I got the email that the app was ready for sale, it appeared in the app store about 18 hours later.
