New curriculum, no money for new books

My school district has adopted the new Maintenance and Light Repair curriculum for the Automotive Technology classes. The textbooks I have now are from 2004, and do not address many of the required competencies of the new curriculum. Further, owing to the numerous technological changes within the automotive industry, the textbooks also fail to cover important systems, such as tire pressure monitoring systems, backup cameras, green technology, etc. Presently, there is no money available for the purchase of new textbooks. A classroom set of 25 will run about $2000, and would have to be shared by all classes. In order to have enough books for all my students to sign for one, I will need around 125 books. What is more, the software that we use in the shop for scanners and alignment machines must be updated every year or so. Each update costs several hundred dollars. I am presently working with 2008 software. Don't get me wrong, we have great equipment. We service in excess of 150 vehicles each year, mostly those of teachers and parents. We are not allowed to charge labor, however. We can only charge a $12 shop fee to defray the cost of eye-protection, hand cleaner, rag service, lost/stolen tools, etc. We do get federal funding through the Perkins Act, but that must be spread among hundreds of programs. I would like to be able to set my class up with the proper textbooks and most up-to-date software. My students have gone on to work at Firestone, Jiffy Lube, International Trucks, Autozone, O'Reilly's, Midas, and other repair shops. My class prepares them to be self-sustaining, productive members of the workforce. Please help provide them with the tools they need.
