A good place for language (and other) courses is the Volkshochschule. This is a system of community colleges present in all sizable German cities. Most other language institutes are more expensive but are worth checking out if you don't find the fitting course. The bigger Volkshochschule should offer a good array of both intensive and slower paced courses. But it can also depend on what teachers they have available. Or if not enough people sign up for a given course then it can be cancelled. Use Google to find the options convenient to you and see what they offer. There are companies that offer private tutoring in most cities as well. An even cheaper option can be to put up a notice on a pin-board at the local University. Often students make money tutoring around the 15  - 25 euros an hour range.

Even if you manage to find a job writing in English, it is likely you will need passable German to get along both in work and private life. One can survive with English but one is limited in so many ways not to learn German.
