Injector Replacement/Upgrade

It appears there's absolutely no information on this forum regarding the work involved in replacing the injectors. I'm going ID1000s which should be plug and play wiring and fitting wise.
Just wondering if this is something I can do myself or if I should get a mechanic to do it?
Any guides or cars where the process is similar enough to apply to the Liberty would be great, or tips from anyone who's done it before
