"I can't pay much because it's my own money." I'm so sick of hearing new publishers say this. Of course, it's your own money, it's your business. If you open a candle store you don't expect the candle makers to give you free candles so you can turn around and sell them at a profit do you? So why should writers give you their words?
Every small business I know operates at a loss the first year and sometimes for two or three. It takes time to build up a business of any kind. And it takes money. If you're not willing to spend your own money to make a profit why should writers trust their work to you?
Please stop whining about YOUR money. Either you're going into business or you're not. Make up your mind and do the work and make the investment. Will you fail? Maybe. But if you're willing to invest the money in your writers your odds will be a whole lot better.
End of rant.
