Hello, and welcome to the forum!
My first suggestion is to really do your research, and educate yourself as much as possible. You should find that this forum is extremely helpful, and will give you just about all the information you'll need to give your piggies a happy and healthy life. All you have to do is take the time to search for it, and read through it.
What do you have for supplies? What type of cage do you have, and how big is it? What's your plan as far as feeding is concerned (hay, pellets, and veggies)? Where are you thinking about adopting your future piggies?
Congrats on taking the first step to guinea pig ownership!
