Create Event Listings & Backlinks for Event Websites

I need help to create event listings & backlinks for three events' URLs as listed below: a) [login to view URL] b) [login to view URL] c) [login to view URL] I need the person to create at least a total of 20 trade listings and 20 generic listings for each of the URLs. The total number of listings is therefore 120 listings. What do I mean by trade listings? Below are two examples of trade listing for event (b) above: i) [login to view URL] ii) [login to view URL] What do I mean by generic listings? They are event sites that are suitable for all types of events, for example: i) [login to view URL] ii) [login to view URL] Only whitehat methods should be used.
