Do you have a place to install the engine yourself? Got a decent garage? Fall is coming up, temps will be dropping, and I'll have a few months of downtime from my racing program to help out someone with an engine swap. I've pulled out and swapped lots of Subaru engines (putting in a new engine/trans this weekend in my race car). I'll gladly pitch in and help you out with an engine swap if you want to go the DIY route. With a complete engine it really is pretty simple. Just gotta plug everything in the right spots. Just takes time.
