I'm in the same situation except I do a lot of side work. Network with other tradespeople you know and ask if they could use help on nights and weekends. Don't turn down small patches or crappy remods because they could lead to full basements or even houses. If you produce a quality product word of mouth will kick in.
I use Thumbtack they are great way get side work only thing is you pay per lead but only if they reply for you to give them a quote and if they cancel and they did not tell you they fully refund you back your money. Its better then All other lead companies out there. Also Craigslist is another way its free but if you run an add they charge know $35 for 30 days
