Translation and female voice over from English to German

I'm seeking a professional to translate and provide voiceovers for two online training videos from English to German. The first video is 35 minutes long, and the second is 25 minutes. The English script will be provided for reference.

I'm looking for a native German-speaking female voice (no computer-generated voices). Please submit a voice sample for consideration.

The task includes:

Creating two high-quality audio recordings.
Ensuring precise timing to match the original video, avoiding gaps or white noise for seamless integration.
Please include in your proposal:

A reasonable price quote.
The software/programs you use for recording and editing.
Your availability to start.
An estimated timeframe for project completion.
I'm looking for someone who can begin as soon as possible.
