Many years ago I tried getting listed by submitting, it never happened until I got a link up to my site. So my experience is useless, my guess though would be 2 months after submitting, if then.
Site submission is a waste of time, although it doesn't hurt to do it.
Just find someone with a google indexed site and have them link to you, it doesn't matter what page, how many pages, or anything else, as long as there is a link to you. search engines work off of links, it's how they spider the web.
