Possible number of names from a certain alphabet

I am trying to solve the following problem, but I am a bit stuck. The question is as follows.

The language of a certain island has only the letters A, B, C, D, E. Every place name must start and end with a consonant, consist of exactly 6 letters, contain exactly 2 vowels, which may not be next to each other, and cannot have 2 consecutive copies of the same consonant. How many possible place names are there?

From what I have established, since the start and end of the place name has to end with consonants, there are $3^{2}$ = 9 possibilities for this.

This results in $\ ^{4}C_2$ different choices for placing the vowels.

However, I am a bit confused after this.

Any help would be greatly appreciated.
