Invitation mailer for corporate event

We need an invitation card (mailer) to be designed. The target audience are IT-professional in large organisations. The event itself is about SAP security and will take place in a classic location in Frankfurt Germany. The format for the invitation is DIN-lang, folded, full color 2-sided. We need to place the invitation copy, the agenda and a registration link on the mailer, as well as Logos of 3 sponsoring companies. Also, ideally we have room to personalize the mailer (i.e. have die address printed right on the card) Lastly... this is a rush job, so I would prefer working with somone in my timezone (Germany)
