Slaya,
Murphy here has good advice, not knocking it.
However, I think the first thing you should do is go to your local bookstore or library and get some books about ponds. Helen Nash is a great expert on the subject and has written a couple good books. That will give you the basics you need to undestand how your pond ecology and plumbing and such works. Once you get the basics down, it's not that hard, and very enjoyable to have. Can't beat hanging out by the pond on the weekend or after ahard days work, it's agreat stress reliever.
1 more thing, get used to the fact that sometimes, you are going to have to get in the pond and do stuff, like spring cleaning. Ya might want to invest in a set of fisherman's waders, i use them regularly.
