I call b.s. on your b.s.calling. The engine hoist would be a few hundred, everything else is just bolts. Another few hundred for a comprehensive socket/wrench set and you're there. You could probably buy an engine from an eBay car breaker with the remaining cash.
I've done a land rover series 3 which are heavy cast iron, but dead simple: a few cables, water hoses, two engine mounts and the gearbox bell housing bolts and it's out - maybe a couple of hours. I also did an Audi a4 b5 2.8 which was a bit tricky - many more electrics (vs about 2 for the lr), power steering, air con, inaccessible ancillaries and no room to work. Whoever says the Germans have no sense of humor has never tried to work on one of their cars... anyway it took a few days but it got done.
