Customized my wordpress website

I need a customization on my wordpress website, Theme I used is KLEO the next level wordpress premium theme. The customization are: 1. Advertisers can place their ads frontend, advertiser can see the availability slots on a particular days and they can book it online. Advertisers can actually select a specific country where the ads can be place. ads is placed on the widget area on all pages except homepage. 2. On the menu bar, there will be a "My Page" menu where users activity stream can be seen. Users or members cannot allow to see other members activity unless they are connected through, friends or followers. Thank you.
