Really depends what he likes and where you guys live.
Generally, I would recommend nursing. You can become an RN with an associate's degree and there are many RN to BSN programs.
RN starting salary is generally in the $60,000 range (higher for high COL such as CA and NYC, etc.) Keep in mind, this is just the base pay. There is usually opportunities to work weekends/nights/OT and receive a significant bonus in pay through shift differentials. For a career that you can begin in roughly two years, it is a great one and in high demand (again depending on area, some have a glut.) Also, if you go the associate degree route, which I recommend, you'll likely utilize a community college for the degree which saves a lot of money. Furthermore, hospitals tend to incentivize nurses to go back for the bachelor's degree and provide tuition assistance. (The amount varies, my last hospital offered $1000/yr. while my current one has paid for half of my bachelor's and is now paying for my Master's.)
However, working on an inpatient floor/hospital as a Registered Nurse is not easy. It can be very stressful, but generally, you'll do 1-2 years on a generic medical surgical floor and then lateral out to a better floor or go somewhere much less stressful. :) For example, I worked two years on a transplant floor working nights/evenings/days/holidays/weekends...you name it. Then I worked in a outpatient clinic, now I work as a supervisor in said clinic. 9-5 M-F. My quality of life is great and the pay and fringe benefits are solid too.
The nursing field is very diverse. You can go into education, management, different specialties or go on to become a Nurse Practitioner (~90k-110k+) or CRNA (~150k+) The possibilities are endless. I have only been an RN for five years, but this, so far, has been an excellent career with countless opportunities.
Also, I am a straight male. Don't let the gender bias idea discourage your husband.
