Stuck with before and after video article content

Hi, guys,
I feel kind of stuck with video articles. I'm recording articles with voice over and screencast and I are aiming for high-quality sincere content. I'm reading the articles and then edit them to remove the places where I fck up. The final result is quite good but I'm missing a vital ingredient.
And that is what the heck I should say before or after the video.
The beginning is usually:
-Hi guys and welcome to another video article. Today I'm going to talk about the top 10 blah blah.

The end is usually:
-Thank you for watching and I hope you liked it.

After the second article, I'm going to add a call to action recommendation of a product like:
- I can really recommend 'affiliate product' it has benefits blabla. Go here to buy it (show the buy button at the bottom of the merchant landing page)
-Just click this button that you find below this video.

I want to be able to evolve the beginning and the end a bit more to build more trust to the viewer and I need more ideas.
Appreciate your help on this.

I'm thinking that asking questions could be really good like:
Have you found an e-book about content marketing? If so please let me know what book you bought and what you like about it.
If you bough the e-book I recommended in the previous video then what do you think about it? Is there anything that I can help you with?... (mail merchant if you don't know)

I take it that most of you aren't interested. However I believe if I nail this then I will actually be able to finally make money with this and with many other things as well. Bing, Adwords, Facebook etc is the easy part. Content creation is the hard part. The lack of curiosity when things get boring is why we fail. Some things are necessary but boring if you want to make money. If I didn't know this and I were just visiting this thread I would probably think: -Fck this I have no idea. And then I would move on.
You can't focus because it is inconvenient.... Maybe that is the thing you do wrong.
