A designer friend of mine wishes to basically "hire" me to write poems for digital prints that she will sell. It was initially a business idea we came up with together, but honestly I don't have the time nor the same passion or commitment towards it, so she's suggested simply taking over and paying me for my writing. Sounds good to me. But how much do you charge for a poem? I've never been paid for my writing before. These will be poems based around a given name for a baby. I'll be paid per poem. I have an idea of what she will charge for the print unless she's significantly changed the prices since, and she's a friend and mum of three, so I wouldn't wanna overcharge her, as she's a friend first. And actually, what about continued sales of her prints afterwards? Do I ask for a percentage of whatever she sells thereafter? How much?
