/HELP!/ Ad insert for RSS posts

I got RSS feeds scraper for my website and I want my in content ads to display automatically for every new post.
More specifically I want 2 banner ads between the content, the first should be after the 1st <p>, and the second should be inserted after about 40-50% of the content.

I tried 2 plugins: Ad Inserter and Ad Injection.
I can easily set the ad after the 1st <p>, But I cant seem to find an option for the second ad placement ( after 40-50%).

I cannot set the second ad to be for example in the 3rd <p> (somewhere In the middle) because some of the posts that get scraped only consist of 1 <p>

This is what it should look like:

(I am not good with paint, I know)

Ad Inserter supports insertion at relative position in posts. Use value between 0 and 1 for paragraph number. In your case 0.5 fo 50%.

I solved my problem, I used this plugin:
