Photography logo designs?

I'm an amateur photographer in need of a logo for my pictures. I've been taking regular sunsets and scene shots on a basis, and have been suggested to buy a professional camera. The Nikon D3100 suits my budgit so far. But before I start taking pictures with it, with some studying and practicing, of course, I would like to have a logo that I could add to them.
Does anyone knows a simple, but yet, advanced software, website, program, etc. That can do so?
Nothing fancy. Like this: TC (my name), and "photography" under it.
Something like in script that would make it seem like the 'T' and the 'C' kind of joins together…
P.S. I'm adding a sample that I've been messing around with.
Any help or volunteers would be highly appreciative.
Thanks!

You could use Inkscape. It's free http://www.inkscape.org - it's a vector image editor similar to Adobe Illustrator. You can turn text into vector objects, ungroup them, and reposition them to intertwine the letters like a monogram.
Here's a screen shot of Inkscape in action:
