Do you guys do all the work by yourself?

Hello, I've been here quite a lot and as you probably guess I've just recently took action (took couple of times before but faild) now ine of my biggest questions is do you guys do all the work by yourselfs? (On page seo, content, of page seo, link building and etc.) Or you hire someone to do that for you, I'm asking this because it can cost you a fortune if you do hire someone and if you do it alone it may be low quallity or you could do it wrong and you just spending your time on this and the results will be awful. I'm asking this because I've tried to do everything myself and the results was zero to 10$, maybe it was because of lack in knowledge anyway I had better sucsess with ebay than IM, but ebay isn't stable if you don't have good prices without branded items and if you do competitors will report you and you will get banned. This is why I always will prefer IM even that I failed couple of times.

If you can afford to out source some of your work then do so. Allows you to focus more on other tasks

Yes, in rare exceptionally cases I outsource.
