I know that bidding directories have gone out of fashion but I have one still knocking around and it has some categories with no listing in it. The directory is called Simple Link Bid Directory. I am offering you free bid in the directory, this offer applies ONLY to categories that are empty for example the finance category . I will consider creating new sub category if you have a niche I have not created already. So, submit your site, the description of your site MUST BE A MINIMUM OF 100 UNIQUE WORD you can bid $5, when you get to the payment page, exist without paying. Send me a PM, if your site meet the above criteria I will approve it. Thanks
