Maybe I’m not seeing someone right. Sorry. If you’d rather not do it cuz you don’t think you can handle it, DO NOT OVER PRICE IT! Just tell the lady that it’s currently to much for you to take on.
If you don’t wanna do it just cuz you don’t feel like it’ll be worth your time, then sure, price it as high as you want. When you overprice job to avoid doing them, sometimes people surprise you, and then you get stuck with it.
