It would be illegal for most knowledgebale practitioners to teach you, as it is against the law to teach a minor without parental concent. (I say most, because their are some very knowledgable minors out there and from what I've heard, their are no laws against minors teaching minors)
A wonderful post about that by Lark is available below:
I would suggest "Google-ing" druidic beleifs or trying to find some books about it at your local library. Thier are muiltiple PDF files you can find on the internet about it, as well as websites, book previews, articles, etc.
Also, from what I've learned, a coven must have at least 3 members to be considered a "coven" but ideally has 13 members. As you only have two members, you would be called a "working couple."
