If you want it easy, go for territories. If you want to make a profit, go for accounts servant.
Accounts servants is fairly easy I think if you're good with a computer. I just knocked everything in at once every month (1h of work) and a spreadsheet did all the calculations and then I just printed it out - finished. Never any discrepancies although the CO did complain that he couldn't verify that I did it every week because there was no written record. You don't even have to deal with anyone and if you have a simpleton as assistant you could even have the funds for world-wide work disappear.
I would say myself, avoid magazines like the pest. Because you HAVE to do that at the KH and inventory hundreds of books and magazines every so often (every 3 months) and deal with complaints about why their special orders they placed last meeting isn't in yet. On the other hand, you could also maintain a hand in the influx of 'aspiritual food' as I did, before I left I regularly destroyed hundreds of pamphlets and magazines.
They're all mind-numbing stupid jobs that anyone could do so you're kind of stuck. I myself would've just refused the MS appointment, let them deal with their own shit.
