One of your major choices is how much you want to specialise, vs be a general service. I expect you're in the phase of discovering that. Now, with the disclaimer I'm just a random guy who knows not-much about business - and is just a small hobbyist electronics guy - it seems clear that your stiffest headwinds are at General Service. I would be leery of how much success you'd have there, because general PCB service is something the world has A LOT MORE of than it had 10 years ago, and the economics are on balance unfavourable to you.

But to (very slightly!) paraphase you, you think it's important to focus on drones/defense and other nationalist areas where the future is canted toward you, and while that is not an area I'd enjoy working in myself (no personal judgement on you, but I'd rather spend my life doing things other than conflict and war), that is clearly what you know to be your first-rank business chance.

A lot of the hype is overstated, and I have been in drone world since 2014, but because of the weaponization of them and the global atmosphere of militarization, there’s a LOT of money pouring in now, so everyone wants a piece of that cake. In reality, their (the fpv ones specifically) success rates are around 1/10, but only the successful ones are shown for obvious reasons.

Also, I did mention back in 2020 that drones are the only practical type of robotics compared to others, although I meant for good purposes not how they are used right now.
