What is the best thing to outsource?

Hi guys - I'd love to get your opinion on something.

I've been working as a small business accountant in a large firm for years and I'm finally about to take the plunge and start my own thing.

There are two main areas I'm looking at that I know really well and that I think are currently really under delivered: bookkeeping and social media management.

Which of the two would you guys be most keen to outsource?

Which would you be willing to pay more for?

Are there any other services that you would always want to outsource no matter what?
