Edit video describing what is inside of my membership site

I have created video that describe what is inside of my membership site. I shot three parts that I need to edit and combine together to a single video. I need also to create short intro. The final video will be about about 10-15 minutes long.

The final video will be placed on this page: http://www.simple-stock-trading.com/richards-trading-club/
Generally I need to make a nice video for this page to show what is inside my membership site.

If you need some more clarification for your proposal, just contact me.

Clarification1:
==============
Three parts of this video consist:
1st part is video I personally speaks into camera (Smartphone) - approx 1 minute
2nd part is screenshot video describing what on on the web (screen recording) - approx 12 minutes
3rd part is me live again saying subscribe below and bye
You can see them here: https://www.dropbox.com/s/2qjk3jtpq6jbqh7/Video-What-is-inside.zip?dl=0

I need to combine these three parts into a single video , you can include some effects to make it nice etc.
