Help me find a theme

I am new to WordPress, I am using a hosted version at 123-REG.

I have just setup a basic site, with one article as a test, using the Ignite WP theme;

What I am having problems with is finding a theme that I really like, most of the free themes you can tryout are limited in features and configuration so its difficult to work out which theme will do what I want; there are so many to check out.

Take the blog page on here;

I like its open wide format but would want to change the colours and I need to be able to insert pictures and have the text float around them. From the page source its a Weebly themed site.

Can anyone suggest a WordPress theme that is similar, paid for or free ?
