Channel Background Help


The Techy TV
I have two new channels that I am working on Designing, Marketing, and Branding. My main question is how I should design the background of the two. My niches are

Technology Tutorials
Making Money Online With HYIPs

Just give me some advice on how I should design the backgrounds for these two channels.
There are a few people who really know a lot about back grounds. Michael for one. I would wait for his response.
Just download a YouTube template and use a little Photoshop to customize it. You can find one on VexrDesigns YouTube channel (I cant post links yet)
