First of all, may Hashem bless you with much joy and happiness! Circumcision is, as you know, an extremely central milestone in the life of a Jew. Aside from the fact that it is a commandment (the first given to a Jew!) it is also the entry of the child into the covenant of Abraham and into the covenant between God and the Jewish people. There are many legal and medical requirements in Jewish law for a correct circumcision, and it would be impossible to explain them all over the email. I suggest you contact an Orthodox Rabbi in Tennessee.
