I am assuming from the librarian sciences that you have an knack for organizing data and a talent for somewhat technical things. From the lit degree that your writing and communications are quite strong.
Technical writer Bonus if you like photography and can include pictures into the techinical writing. I am thinking workplace safety and user manuals. A lot are being put on line now... needs incredible organization of materials and information. needs great people skills too. This is the equivalent of "how to service a transmission"; "how to work with ammonia safely and the company policy and safeguards you must adhere to".
Marketing business writer. I need people that can help write and put together proposals for engineering services. I figure out (with the helpers) the strategic messaging and key points, and write some of the workplan and approach / key beneifts pieces. Then the real work begins as marketing adds in the photography, references, resumes, past project profiles, insurance proof, creates the cover, formatting, cover letter, etc. etc. most from a huge company on line library that must be maintained and updated, and used efficiently on short notice.
Technical writer tends to be freelance / self employed. Marketing communications pays $50k per year here, and goes up. (Junior staff may get less, but their role is much less than stated above, too)
Executive assistant (great at organizing, and writing letters with only a few bullet points from the boss, and getting other people to do what they are supposed to around the office). Starts at $50k. You work up into this role, but some join EA network groups and take extra training, too, to justify hiring. The best EA's are well networked around town and are professionals in their own right.
