Heather,

I would look at LinkedIn and some of the Job opps here for ideas. Most titles for Marketo only roles are

Marketing Automation Specialist/Manager
Marketing Operations Manager
Marketing Manager
Demand Generation Manager (more creative aspects to role)

There aren't a lot of experienced people who are open to non consulting roles right now. As Pierce mentioned, there are many agencies and freelancers who can help you get started with Marketo or manage it for you without a big commitment. Feel free to reach out if you want to speak further. jdhill@marketingrockstarguides.com
