USA Become a Part Timer?

[ChrisinLouisville]

I'm nearing retirement, and due to the recessions effect on my savings and house value, I'm going to need a supplement to my social security and investments. I'm thinking that work as a basic bookeeper/accountant would suit me, but I wonder if there is opportunity as a part-timer or temporary or seasonal employee.I'm not looking for a career, I only need an additional $800 to $1000 monthly to live the way I want in retirement and wonder if this is a realistic expectation in the accounting field.
If you feel this is a realistic goal, what sort of certifications or degree would I need to look at, and are any professional affiliations useful?
Any answers you can give would be greatly appreciated.

Thanks in advance,
Chris
