- Depending on what you mean by "basic programming and CS skills", it may be hard to find a programming job other than an internship. Unless you are in an environment that makes heavy use of math-based languages like MATLAB, R, or Mathematica where you can rely on your math background, most employers will want to see more experience before hiring you as a programmer.
- Software Q/A testing or IT support may be your best bet given your prior experience in IT support and some familiarity with programming. Software Q/A testing can actually be quite interesting and will definitely pay around (or more) than what you're looking for. I would try to look with smaller tech companies that do niche enterprise software, they're quite flexible and open. The best thing about software QA/testing is that you have a very predictable work schedule and won't have to take work home or be called in at odd hours.
- Business analyst is also a good option, but again you may have to settle for smaller or lower-tier companies in the short term as GPA is of unexpectedly large importance for that position.
