Hey, glad to see some interest already!
It's no problem if that movie is already spoken for, it was just an example anyway.
As for pricing, for a standard two hour AV movie, I'd be looking at $200. This depends on the content as well, if there is a lot of dialogue (relatively, for a JAV) the cost would go up.
And conversely, if there is a relatively low amount of dialogue, the price would go down. It all depends on how much time will be required to do the script, but trust me, no one would be getting rich off this.
This may seem steep, but it's actually not, considering the labor involved. To complete a two hour length movie, it would take more than 25 hours of work to do it well, and depending on the quality control and typesetting required it could be significantly above that.
I would not mind working with provided timings but naturally that comes with some caveats. As this is very precise work, especially when there are multiple people talking at the same time or right after each other, the timings would need to be very accurate.
Both accuracy and ease of reading for the end user need to be taken into account.
If I were to have to correct the timings myself repeatedly, I would prefer to do it myself in that case. If you are unsure, you can provide me with the timings of a short segment of a movie, and I can give you my opinion on it.
And with such a provided file, I will translate everything that is marked of course, and I will do any unmarked lines I find during QC, but I won't be responsible for missed lines that were not marked on the script.
I'd give a 25% discount for a proper timing list.
As for completion time, I'd be looking at between one and two weeks for a standard movie, barring any unforeseen circumstances. In case of delays I'd notify you of the reason and discuss it with you.
Seeing how this is an intensive task I'd only take on one project at a time. Others won't be accepted until the current one is already completed, so I can fully focus on it to guarantee a good turnaround rate.
Lastly, considering the fact that I don't have any rep on this forum so I can understand if you're hesitant to go with a dark horse, I'm willing to do a first project here at a 25% discount.
I hope that answers all your questions, let me know if you need anything more.
