I have been doing designing as pure side work along with running a business and working full-time. I would say that designing does me about $3,000 per month but that is on good months. Do all kinds of work, if you can skin vBulletin that's great but you have so many other scripts out that that need good skins and themes so don't limit yourself. Also get into doing full websites, you can pull anywhere between $800-$2,000 per website depending on the customer. Know what your designs are worth and don't sell yourself short.

But more directly my profits help pay for the extras in life :-).
