Startup business. Gardener

I'm currently employed, I earn minimum wage as a gardener with very little opportunities to earn more in overtime etc, also to add to this and the main reason I want to start my own business is because I'm going to become a father in November, I need to add to my income, I plan to start by doing weekend work and as my reputation grows will go full throttle on my own. I need however funds to buy my own tools as my boss won't allow me to use company tools at the weekend, i also aim tondo a garden design course too so that I can offer my clients a full encompassing service. Please help, I want to succeed and find my spot in this world ,
