Hi,
Take a look here:

Seems like want $75,000 for a certificate only. I believe 135 certificates are not easily transferable.
Starting a 135 operation from scratch can take from 6 to 18 months.
I have done Letters of Compliance and manuals for 135 operations and feel free to contact me. I'm new here and not sure if you can send me a private message.
