Hi Addie,
I'm enjoying reading your posts because we are at about the same stage of our gig development (side gig for me).
I have struggled getting content to clients electronically. Even the ones I deem tech-savvy run into problems with firewalls on their companies' networks, and things like that. I now do everything by flash drive unless otherwise requested. I have found some good sales on bulk packs of 16GB flash drives at Office Depot. There is even an option that I haven't tried yet, where they will print your company logo on the flash drives, and they actually work out cheaper than just buying the off-the-shelf ones.
I think there is some benefit to seeing your client in person when delivering the finished product, too. I know it takes more time, but when practical, I think it's a nice touch. I've actually received a couple free lunches and beers this way! Depending on the job, this also sets up the opportunity to be paid in cash... I'll leave it at that.
As for photo editing software (from a later post), I like Lightroom. The cloud version is great because I can go between devices and have my library available on all. I use an iPad Mini 6 with my drone, and started playing with editing on it, since I can do it on the couch, or wherever. I thought the screen would be too small, but it works great. It is my go-to now. The Apple Pencil is very useful for editing, too.
For video editing, I have tried Premier Pro, DiVinci Resolve, and others. I am not an Apple die hard, and actually prefer Android and PC, but for certain things, Apple just wins. I found Resolve to have a steep learning curve and is very resource demanding of computers for editing and rendering. It is also loaded with features I will never need, but add to the complexity of navigating the app. Even my Macbook Pro will not cleanly scrub through video, and takes a long time to render. I even built up my Dell laptop with a powerful processor, 32GB RAM, and a decent video card, and it is still struggles with certain video processing tasks.
Incredibly, I downloaded Lumafusion on my iPad, and it is awesome! Editing is very intuitive and the processor in the iPad Mini 6 rocks it effortlessly. I can smoothly scrub through clips, and rendering takes about 1/4 the time it does on my PC or Mac. It doesn't have as many features as PP or Resolve, but plenty to suit my needs. It can even be set up with an external monitor where you manage all the controls on the tablet and display the video window on the monitor. I can edit video much faster on this setup using the Apple Pencil than I can on my Mac or PC.
Okay, my two cents worth turned into more of a buck-fifty, LOL! Good luck in your venture!
