If you're a strong writer and willing to learn some new skills, I'd recommend that you consider writing white papers for B2B companies. White papers are typically 5-12 page reports (including basic graphics) that discuss a solution to a business or technical problem for about 85% of the document and how a company's service, product or technology solves it for the last 15%.

As a new grad, you are unlikely to successfully "author" a white paper, but you could use your writing skills to capture, organize and present a subject matter expert's information. Two great ways to do this are 1) interviewing the people at the company who know the material but don't have time to write or 2) using information from one of the company's webinars as the basis for the white paper. You could offer add-on services like blog posts and social media blurbs to promote the white paper.

Unlike freelancing blog posts, which is popular among new grads but typically only pays $25-50 per post, you can typically charge $400-$800 for a well-written white paper.

To get started, you should choose an industry area that interests you and start reading as many white papers in that niche as you can find. Get a feel for the language, the style, the length, the approach, etc. Try writing one or two from webinars on spec to practice your style and get some experience. Then start reaching out to marketing directors and marketing consultants in the niche to build a clientele.

Good luck!
