I can do that.The second video you have shown which is 19 seconds that's kind of impossible in the amount you're paying but I can create a small intro with your website's logo and related design.I can have a small audio clip of your website's name.Let me know if you want me to do it.
I just needed a video for 6-7 sec not for 19 sec that was just an example. secondly do you have an Portfolio? Or Will you make changes in the Video after creating it, If Needed?
