Our work truck needs repairs

Thank you all so much for your help!! We made our goal, your all amazing! Howdy yall! We do handy person services all over the valley as well as fire mitigation and gardening to help earn a steady income for our trans haven alpaca ranch. Our only work truck and key to our income went down last week and we could really use a hand to get it up and running again. We drive the heck out of it and need it for literally every job we do so our income is suffering without it. The mechanic says we need to fix a massive oil leak, plus replace the variable valve timing solenoid, alternator, serpentine belt, water pump and replace the battery. Any help to get us back to work is appreciated tons!
