Create Subtitle Files for DVD (.sup/.sub)

Looking for someone with experience to take existing script that has been translated into English, French, German, Italian, and Spanish and create the .sub/.sup files and create the DVD masters (not the DVD layout but create working DVD's with each working subtitle). YOU ARE NOT DOING THE TRANSLATIONS - THIS HAS ALREADY BEEN DONE. Please PM me with relevant experience / what software you would use so I know what you are talking about. If you have not done this before or do not have the skills necessary please do not bid. This is not a project I want you to learn on unless you plan on giving me a super great bid lol. This is for a feature length documentary - 86 minutes, 980 lines. Compensation includes winning bid + IMDB credit. Thanks!
