This landing page is too busy with the animated backgrounds as you scroll.
From my short look, I think you will have a hard time finding that person who has no time to read an article and instead wants to outsource that to you. You would do better if instead of having a human summarize the articles, utilize one of the many NLP Summarizers out there (they aren't great but they scale). More about that here: https://en.wikipedia.org/wiki/Automatic_summarization
You can charge users for credits, then base how much an article costs on its length.
For a product like this it is always best to hide the true cost behind credits, then charge tiered prices for the credits.
Buy 100 credits for $7 or 1000 for $25, etc.
You will then want to explain WHY the person NEEDS this, and probably in autoplaying animated video with a professional voice over actor reading a script that is also close captioned in the video (test the autoplay though. some audiences convert like crazy on it, others bounce).
Then have 3 product offerings, NLP, Human Written and a Voice Mail type MP3 recording of the summary.
Most people will go for the NLP, but some will pay for written, and you can out source that to various crowd sourcing platforms for about $1. For the voice mail you will probably have to pay $1 for the summary then $3 for a person to read it.
Credits should be purchased on a subscription plan for a discount over the one-time purchases, and you should offer a few sample outputs and get testimonials from people.
That should get you started! If you have any other questions, let me know.
