Buy a bottling bucket and a bottling wand, it should cost you less than $15 combined and will save you a ton of pain. Cut a small (2-3") piece of 3/8" beverage tubing and connect the wand directly to the spigot on your bottling bucket, so that it looks like this:

Notice that I put it over the dishwasher with the door open, the door will catch any spillage. Take sanitized bottle, raise to bottling wand, fill, and set it aside with a cap sitting on the top. Once you've done 6-12, cap a batch. Repeat until your bottling bucket runs empty.
