sending serial email to filmproductions

Hello, I'm from germany and develop software for filmproductions. We have a eMail list with 50.000 filmproductions all arround the world and want to infom them about our new products. We are seeking for a networker who can send a text-file (eMail) to these 50.000 addresses via his own provider in india. We have these jobs sometimes a month - if your working good, we do it again and again, always different email lists. Are you interested? Please contact me
