Hello,
Thank you for going through this bid. I have a lot of experience in this segment as I have worked with PGP-BES service providers in UK, Netherlands, Sweden, Canda etc. You can check out my profile for some of the comments and ratings that my PGP_BES project previous employers have awarded me. I can help you with the entire setup right from identifying the best servers (People prefer countries like Russia, Mexico, Panama etc for PGP-BES servers) to SIM cards and licenses.
Also with security as I know exactly what kind of attacks the infrastructure is prone to.
I believe information sharing should be low cost and even free. Lets catch up to discuss more on your project so i can gather your requirements and give you insight on how the existing players setup and run their businesses. The market is ripe now with the big player form Netherlands falling.
Thank you,
Sam
