Create a video bumper

I need to create a short animated video bumper for a logo. An old version of the logo is attached. The new logo will be very similar to the current logo. I'm looking for a short video bumper today (3-5 seconds), and will need at least 2 more in the next month. I'd like for the same individual to do all of them. The videos are usually 1280x720 and I'd like the animations to "fit" well with the overall logo designs. Please provide a link to your portfolio (if it isn't on Freelancer). Thanks.
