New Computer For Digital Art!

Hello everyone I’m Tiki. I’m a digital artist and illustrator. My current computer (which is a laptop) is on its last leg. Its very touchy, which is bad for me because I'm in the mitts of illustrating a second children's book, unfortunately my laptop thought it would be a great idea to stop functioning properly 5 pictures away from finishing the illustrations. This time around I want to invest in a desk top computer, instead of a laptop. I just do too much art and use the laptop too often for them to last long. I need some help getting the money for a new computer since finding a job has been extremely hard.
Anything and everything people can donate will be appreciated!
