Yeah, I recommend him to start! For me it's VERY small business - just one customer in few months and most of them want some help (for which I sadly don't ask for money that I need for studies).
If he wants some marketing eBooks (mostly e-commerce - the easiest way to advertise his services), ask me
Or check out Ewen Chia's book (only $12) - it gives good & useful info on internet marketing & normal marketing - with it, I've improved my business! And I don't advertise in the web or in real life prints/magazines, only by mouth-to-mouth lazily.
Good luck!
