Blogging Help

I have been attempting to re-design my blog with blogger. I want to make a navigational bar. This way I can have my two blogs connected. I want to be able to use my own color background, and to make my blog header with a graphic design for my own choosing.
Some of you bloggers did this yourself. I was wondering if anyone would like to do this is their spare time,and is handy with the technical side of the blog. I am not and I would pay you for your trouble. I have tried to follow directions on the blogger tutorial and it just doesn't do it for me. I am desperate!!. All of you that personal sent me emails to try to explain it to me have been great. But I just don't get it.
