HTML/Coding for Tumblr - Easy Job background changes /Layout

Hello - I have a Tumblr but I want it to really stand out, I have been lucky enough to have some great illustrations drawn especially for the blog and I would love these to run through the back and main pages without disrupting the text. I also have a title banner I would like inserted. It would be great to get this done ASAP as all the content is there and I have everything you need design wise scaled up and ready to roll. If you would be up for this please let me know, price negotiable.
