There are two parts to this.
The first is the Advertisers page with details of the advertiser.
So you need to create a Custom Fields Group which you assign to the Advertiser post type and add the custom fields you require, for the logo, url etc.
Create some content, i.e. some advertisers and some listings.
When you create listings you should see a field to set the parent advertiser. Do so for each of your listing posts.
So now you should have some advertisers, and these advertisers have some listings, each of which specifies the parent advertiser post.
Now, create a new View to display listings (choose the option to display all posts when creating the View).
Add a post relationship Query Filter to show posts which are children of the post where this View is shown.
The design the Loop Output as you require, e.g. to show the listing post title and anything else you want to appear in the list of ads shown on the advertiser page.
Now create a template for single advertiser posts. Include the custom fields for logo, url etc., as required.
Also, insert the listing View you just created.
Now when you visit and advertiser post using this template the View will show the child listings of that advertiser.
That's pretty much what's involved.
If you get stuck at any particular step, let me know and I can elaborate further.
