I build web sites and write stuff. It's what i'm good at. It's what people pay me for. Then there's the other stuff that needs to be done, book-keeping and accounting for all of us, maybe banking, paying staff and all that entails if you employ them. You know the stuff - it has to be done, but you're not necessarily very good at it and hate spending your time doing it instead of doing something which earns you revenue. Outsourcing may be your answer. You carry on doing what you're good at and pay someone else to do the things you don't want to. Because you're paying an expert to do a job, they can do it a lot quicker and more efficiently that you, so it may not cost as much as you think. Even big companies do it if they believe they can get things done more cost effectively by someone else.
Write something about yourself. No need to be fancy, just an overview.
