Hi there, I'm Matt Sergej (you can call me as you wish) and would like to help you - yet you need to decide what video do you really want.
For financial based websites videos with "doodles" (hand drawn animated images) can quickly lose seriousness - and it might be better to have the actual website screencasted to show a particular or few specific actions one can take by using a website.
Other non-financial websites can of course get traffic with doodle videos since the aim there is promotion with a slightly funny note. The latter cannot be a biggest takeaway for earning money online websites.
Yes, I have experience in both type of videos and can also create PowerPoint based animated videos - just not using Adobe Effects for example.
Regards,
Matt
