MS Access developer - worth the time?

[21TonyK]

Long story short. 20 years ago I was in IT, started on AS/400, Novell them moved onto IBM centric stuff and latterly MS products etc Did quite a bit of development work over several years based around MS Office (Access/Excel), medical systems, finance, etc Nothing too major but reasonable scale stuff.

I have about 15 hours a week completely spare and given I've got 12 weeks to get back up to speed is it worth brushing up the old skills and touting for work online? Just something to keep my mind going and get paid at the same time.
