Generally websites/directories do not link to the same site more than once. However, It is possible to get one way links from a single website if it is social networking site / community website. But it is not beneficial as Google will take it just one vote in favor of your site no matter how many one way links you have from there.

Either you should submitting the site in variety of directories and in the relevant categories only for sure. You can start with this list of 17000 web directories

May be it is of help to you !!!
