I'll give you an example of my workflow when it comes to folders and maybe that'll help.
Last Light Films >
Brian & Stacey Di Giorgi Wedding >
Day 1 10-17-2014 (For projects that take more than one day to film, I make separate folders for each day.) >
(Folder #1) Clip >
(Folder #2) Roll >
(In the Roll folder) Camera One - Panasonic, Camera Two - Nikon >
(In the Clip folder) S01T01 (for Scene 01, take 01, taken from my external recorder.) >
In the folder titled Brian & Stacey Di Giorgi Wedding, I'll have my project saved and anything else that the programs that I use (Adobe Premiere, After Effects, so on) will need.
I hope this helped and gave you an idea of how to organize your folders better.
Your new rig seems pretty good, except that you definitely don't need 32 GB of RAM. I recommend either 8GB if you're working with 1080p, and 16GB if you're working with 4K. Anything over that will give you diminishing returns and will waste your money.
Finally, I recommend going to NewEgg.com and buying your PC parts from there and having them shipped to your house and assembling them yourself. This will be much cheaper on your bank account.
I'd like to add a personal favorite of mine.
Becoming the Reel Deal - Evan Luzi
I'm not sure if this has been pointed out, but it may be a good idea to film your actor swimming, and then go to a local pool, or even have him swim closer to your camera so that you can get some foley of him swimming. In post, you just need to use the foley of him swimming over the footage of him swimming far away. But you don't want it to make it sound like the camera is right next to him because it'll throw off the viewers. Personally, I would turn down the foley effect a little bit so it'll give the illusion of better audio without it being obvious that you've done the effect.
Good luck with your film!
Good luck finding an editor.
I'd love to try my hand at it and see what I can come up with, so if you'd like to give me some practice, my email is LastLightFilms@Gmail.com
Hi Tsering. You could browse the internet for a free editing software. Macs come pre-installed with iMovie, and I'm pretty sure Windows comes pre-installed with Windows Movie Maker. You'll have to import all of your media into the program, and drag the footage into a timeline, and then make appropriate cuts to trim up your footage. Whatever software you plan on using, you could open up Youtube and find a basic/beginner's guide to your program.
