[PAID] Additional non-repeating Nth positions for Ad plugin (updated)

I modified the initial post a bit. It looks like my initial budget guess wasn’t realistic.

Also I removed the mockup screenshot of extending the House Ads interface, as that would surely require hacking or forking the Ad plugin codebase.

It’s looking like what I need would have to be accomplished via some clever Javascript and CSS. I noticed that there is a CSS class for each post number, which I assume would help with the modified logic I need. I wonder if it would be possible to take advantage of the current Ad module code and set N = 1 and then suppress/hide the unwanted instances after that with Javascript and/or CSS. (Not sure if <script> tags can be added to House Ads? This post says probably no.)

I found some similar requests here, so it looks like this functionality would be useful to the community:
