Animation - creation c. 2-3 minute clips 4 biz tutorial output 4 mobile & tablet

I'm looking to have some animations created. I've had some done so far, my previous designer / animator did a great job however with FT job and baby has ran out of time to do things in his spare time. I'm looking for someone to continue a style theme - I can show this to those with the right skills / before giving out a job. I need someone to create animation, pull in my logo and blend voice over. Tutorials are for senior executives how to look for a senior job, how to get a promotion, personal branding, networking / political alignment etc
