Sorry for this comment, but you may want to ask a pro to watch the way they do it in your part of the country first. Your question is kind of scary because it shows what else you may not know. This is not rocket science, but if you could watch one go in you will be way ahead of the game. This may save you a lot of time and money.
I know you can do it. It can go in easy or hard. The first one is always hard.
I just wanted to throw this out there.
