How can I condense a Source Sans Pro font so the characters almost touch when 30px size?

I have a web site that is using the Adobe Source Sans Pro font.

On the website I would like to create a logo using this or a similar font but I would like to have it so there is almost no spacing between the characters. Is there a way that I can do this just with css or would I have to use another font?

If I need to use another font can anyone suggest an open source / free to use font that I could use for this.

Thank you very much.
