There are several things you could do in order to quickly improve your proficiency:
- Are there any German-speaking Meetup groups in your area? The groups that I have been a member of have a mix of native German speakers and others who are learning the language. It's possible to noticeably improve your abilities in just a month or two of regularly going to the events.
- Podcasts. Do a Google search for German podcasts and you'll find a plethora of options. The ones I always recommend for language learners are from Deutsche Welle.
- Do you have a university or community college in your area? If so, stop by the German department and ask if you can audit a class. Most professors that I know are totally fine with this.
- You could find a German tutor on Wyzant, of course! :-)
There are other ways to practice German, but these are what I can think of off the top of my head. Hope these are helpful, and if you have any questions, please let me know. Thanks!
