You might want to also contact DJ at Cleaveland tool. She is making me a brand new set of RV-4 seats in custom colors. She has an outstanding reputation and is considerably cheaper than the others. Her products are also very popular so she is quite busy so be patient.
Thirded - working with Abby now on my -8A seats and interior, she's awesome and very helpful, and everything I have seen that she has done before looks great!
