There's a reason most replacement springs come with the front bushings already installed. Anyhow, AS you know the hyd press is the way to go and I bet it would be worth calling around to see what a shop would press them in for, but if you're like me, you'll figure a way out...
1.) A large bench vise could be used.
2.) Some folks have had success with all-thread or long bolts and large washers to force the bushings in. You use a long bolt or all-thread with a nut (the same diameter as the stock bolt) , then a large HEAVY washer (maybe a thick piece of scrap iron with a hole drilled in it would be easier to find - your garden variet washer will just colapse), then put it through the spring then through the bushing then another large HEAVY washer, then a nut. Tighten the nut and it pushes the bushing in. All thread works best because it is fully threaded, where most bolts won't have enough threads to full press the bushing in. You can make up for this by pressing as far as the bolt will allow then diassembling, adding spacers to the bolt head side and re-pressing and so on until the bushing is in. Don't let me make itr sound easy. If you're doing this by yourself you will have difficulty holding both wrenches and apply the torque needed to get the job done. Now, if you have impact wrench - that's a different story.
3.) Putting the bushings in the freezer overnight will help shrink the bushings down which helps with any way you do it (every minute you waste after taking them out just causes them to grow back) and lubicating them will help too. I prefer non-petroleum based grease like you should use with polyurethane bushings.
