Hi,
1. On Indie Publishing, just do it. The landscape is changing. Slower/different in Britain, but so what. New worldwide markets will already be open to you and you can write 2-4 books this year instead of the 1 book agents/trad publishers persuade you to do.
Remember how it felt not to be riding the wave of the last property boom?
2. Learn how to format/or pay someone good, get an external editor, get a cover designer if you can't do it yourself.
3. Learn how to market yourself, online, offline and any other which way.
4. Remember it's a different business model. Long-term profits with multiple product lines work best. No finite shelf life.
5. Utilize all sales platforms. Not just one. Amazon and Smashwords et al. If trad publishing offer you a good deal. Take it and either negotiate hard on retaining extra rights or make sure the advance is big enough not to care.
6. I'm putting my money where my mouth is. I've got three books to go up in the next month or so, including one trad pubbed, that I still retain the ebook rights for in the US.
Then 2-3 more books by the end of the year.
Feel sure it's about time we had an Society of Independent Authors as well.
Break a leg, everyone.
