Fix personal truck used for self employment

Do to unfortunate circumstances, my truck is broken and needing major repairs.  Approximately $4000 for parts and $1400 for labor. She is a one ton diesel needing injectors, injector drivers and injector driver module. She is necessary for my on the road vending business to service my family, friends and other valued customers. Your help will put me back on the road to see all of you. Any help will be greatly appreciated.
Thank you in advance, 
Neil
