little image help

well ive been working on my new project that i think is coming along really well. i worked hard on the logo and it turned out amazing. i made everything from scratch.

problem is i really suck with small graphics and i would really appreciate it if someone can help me with a small background image that i use as a background for main titles.

the image is that little line^

first i would like it to be a lighter shade of green, such as the color the quotes text is on the top of the page. secondly i'd like it to slightly gradient/blend with white towards the bottom to blend into the site.

by the way my site is http://Sociophyte.com

thank you for anyone who can help me with this small thing. :ninja:
