The reason behind this is because book publishing seems a more 'stable' endeavour than typical "IM" type business in the IM niche. I'm looking to establish a stable business to bring in a regular income of at least $2500 per month. I don't expect to hit this figure overnight, or necessarily from 1 book, and I also appreciate kindle success depends on a variety of factors.
I'd like to get feedback from any kindle publishers who are doing this figure or greater about how long it took to achieve (I have a fair bit of time to write the books, but don't necessarily want to be stuck waiting if it takes months for books to sell), the number of books published, publishing frequency, pricing strategies, giveaways, getting reviews, outsourcing, fiction or non-fiction being best etc etc.
I'm not asking for book ideas (I have ideas for multiple sci-fi short stories as well as non-fiction books in some niches I'm familiar with), but any insight into the general "what to expect" from existing publishers about income patterns and daily hassles/tasks etc would be greatly appreciated. Thanks.
