Dynamite is a lot easier. Evo apparently lives in Texas, so she should be able to go to the local K-Mart children's gun and explosive's department and pick up what she needs. Then again, a fully automatic weapon (borrow one from a shooting range, quite common in Texas), would make short work of those branches. Weapons of choice in Texas are a bit different than most places. For example, in Texas, automobiles are the weapon of choice for eliminating ex-hubbies.
Ok back to reality, I'd recommend contacting some tree trimmers. You're trees aren't that big and it shouldn't cost that much to take care of them.
You didn't state how high up the branches that need trimming are, so I don't know what's involved. If it's climbing gear, I'd stick with professionals.
If you do hire an amatuer, I'd recommend tying a rope relatively high on the small tree, to guide where it falls. The tree is mostly likely off balance and will just fall to the heavy side regardless of the cut pattern used on the trunk. It's possible that you can just pull on the rope to take down the tree. Use a long enough piece of rope so you don't get hit by the tree or any tree related shrapnel. If you soak the ground around the tree trunk first, you might get lucky and pull the whole tree out, depending on what condition the roots are in.
For the branches you want to trim, there are saws and clippers mounted to poles for just this purpose, but this can be tiring if the branches are relatively large, and where do you store this stuff when you're not using it (unless you can rent it).
Still as others have already posted, seems like getting some tree trimmers to do the job is the smartest way to go.
