Hey, I have a couple of questions. This seems like a nice project, altruistic. You're trying to raise 10k for a finishing fund. Ok. Can you tell me exactly what you need finished?
Here's why I ask. I've worked professionally and independently as a serious filmmaker for about 15 years now. In that time, I have frequently seen the following scenario.
10 people work on a film for a year, and get paid 4 grand to split. Then at the very end, they need a title sequence, or a digital master copy, or a dvd menu, or color balancing, or some technical part of the requisite process that they don't know how to do. Then some outside contractor gives them a quote. "Oh, you need a pro level digitally encrypted drive to drive transfer" and asks for 10 grand to get the job done. The filmmakers, not realizing that the task only requires a drag and drop to accomplish, pay the money, and check off whatever box. Then in traditional capitalist fashion, 1 person who told a lie and did one simple task makes more money than all the people who worked honestly for a year combined. In example, some major streaming services require multiple subtitle tracks for publication. If you knew exactly what you were doing, it's free, and takes just a few days. Ask for a quote from the wrong person, and that one extra day of work turns into a "service contract for the diversification of transcoded multilingual subtracks and synchronization to high grade internal source deck pre cut"......... You'll find a few extra lines at the bottom of the invoice. 740 dollars for transportation to encoding site, etc. But it's just someone willing to lie to you, upselling a relatively minor operation that could be handled for a grand or less, or free if you're hardworking and fairly bright. How much is a cup of soda? It's $2.79 right? It's not. It cost them an adjusted 1 cent for the soda and the cup combined. The cup costs them more than the soda does, and they'll give you a cup for free. I've seen people pay 70 grand for subtitles for a 3 minute web video about a tractor. It can be done with google translate and 70 dollars on Fiverr.
My point is, maybe your 10k in remaining tasks could be done over the weekend for free, by someone with a couple of supercomputers and a spare 75c in electricity. (which I do have available to donate for the right cause). If your "remaining task" is actually just to pay the filmmakers for the work they've already done, I think that's totally legitimate, but I couldn't help you with that.
If you need a little help, and it's within reason, I might be willing to handle some post or mastering tasks for you. I have a lot of gear and experience, and jobs that are a big deal for some people can be very easy for me. If I can save you 10 grand by donating 10 hours, I'd see that as a good use of my time. If someone wants 10 grand from you for 800 dollars worth of work, I'll donate that 800 dollars worth of work. Perhaps that's not the situation but I've seen it go down that way, many, many, times, so I thought I'd at least offer, just in case.
In your upcoming marketing phase, you might wish to refer to the workflow I set up and outlined in the post "save point social media launch" which illustrates how one can fully automate an entire campaign, reducing your workload exponentially. It's complicated, but it's not anywhere near as horrible as managing 20 social media accounts on a daily basis while trying to prep for your next film.
