While submitting my sites to different kind of directories(to analyze the results to post it here for you), I came across some sites that were offering submission of your sites to like 100 directories, 200 directories, 300 directories etc etc.
Make sure one thing never go for these auto-submission services. There is no harm in paying some one to submit your site manually to different link directories but auto site submission services is not good for your site's reputation and SEO. Before paying someone to submit your site, always make sure to confirm whether they will be submitting it manually or some bot is going to submit it. The spam detection systems that every single directory has these days would not let a bot submit your site automatically and your site will be flagged so beware of aute site submission services.
