Hey jessman,
Go easy, read carefully, and follow the old saying. I have always been told; "measure twice, and do the task once, and measure once, and do the task twice." Otherwise, if you go slow, double check everything, you should get it going and not have to redo the job. The last piece of advice....ask questions when you need to. I think you might want to go ahead and get started and holler if you need help. Hey, you did ask for an opinion, so can't guarantee your results, but I think you can do this one if you go easy and read carefully.
