Any advice, I'm in no way looking to do this immediately, just curious.
2. Identify trade shows and other events that are frequented by people in the industry you want to target. Go to those events and mingle with people there and solicit interest. If you have money to spend, rent a booth at the event formally.
3. Go to generic "business mixer" type events held in your city... things put on by groups like the Chamber of Commerce, etc. Mingle and talk with people and solicit interest there. Note: this is less targeted since the audience is more random, so you'll probably get a lower "hit" rate.
4. Speak at events like local Java User's Group, Linux User's Group, Scala User's Group, etc. meetings and meetups. At the beginning or end of your talk, casually note that you do consulting / services around the topic you are presenting on.
5. Talk to former co-workers and other connections of your own and ask them for referrals.
6. Advertise. Facebook ads, Reddit ads, LinkedIn ads, Google adwords, etc. Have a nice website to direct people to if they come looking for you.
7. I dunno, there's probably hundreds of other things you can do, but those are some obvious ones that come to mind.
