Welcome to the forum and good luck with starting a business.
I'd second what Ideasuniversity said about Evan Carmichael and Takuya Hikichi's new ebook "Making your first million". It is pretty comprehensive and a great read for anybody about to get started. You can find out how to get a FREE pre-publication copy elsewhere on this forum - or send Evan a private message about it.
A couple of free ebooks I'd recommend are:
Dotcomology - the science of making money online. An in-depth look at Internet marketing by Stone Evans.
Harness The Power Of Article Marketing by Janet Wilson
Pretty much anything by
Seth Godin, but especially
Permission MarketingReady Fire Aim by Michael Masterson
Both of the above are available on Amazon
OK, that is just a taster to get you going!
Best wishes,
David Hurley
