Needing help with my business

My son Rhylan and I had to move home a year ago and start our life all over. I have been a hair stylist for 10 years, but have always worked for other people. In Pendleton if you're a hair stylist you have to work for your self. Working for your self means overhead, a lot of overhead... Station rent, products, retail, random supplies, etc.. I was only working part time and a second job untill my son started school.. I have now started full time at a new salon called Fusion, and I'm needing my full color line now to keep up with all of my clients and new potential clients. My color line includes all the color I need to get started and all the supplies, but it seems impossible to save $500 to get my color line when I have little to no help at all raising my son. I just want to be able to provide for him and to do what I love, which is hair. Any donation is much apprrciated. Thanks again in advance :)
