Clarify Muffled Home Security Recording

I’m working with a single 45-minute clip captured by a home security camera. The microphone was quite far from the conversation, so the voices are muffled or unclear and there is a layer of distant-voice ambience sitting over the track. I do not need the video—only an enhanced audio file that lets me hear the speech as distinctly as possible.

Here’s what I’m after:
• One cleaned audio file with the voices noticeably clearer than in the source.

Feel free to use iZotope RX, Adobe Audition, Audacity plug-ins, or any other workflow you trust for noise reduction, EQ, spectral repair, and dialogue isolation; the tools are up to you as long as the result is intelligible. If you offer tiered packages, please outline which level you recommend for this sort of distant-mic recording and what each tier includes.

Please also confirm the fastest turnaround you can guarantee once the raw file is in your hands.
