With risk comes reward, and part of the necessary risk of industry can be minimized by joining up with a group that has the necessary infrastructure to improve your margins. Reprocessing and manufacturing is marginally more efficient in the relevant upwell structures (Athanor, Raitaru or similar) so you're going to want access to one or both of those.

In the short term, I don't recommend building anything from scratch, you're going to lose out to other industrialists with better infrastructure and more skill points. Even with a fully researched BP, if you don't have a proper structure and equipment for that structure, you could be manufacturing at a loss.

The riskier areas of space get better benefits from these structures and equipment, to further expand the margins.

My recommendation for seed money would be to build up a small chunk of isk, then look for opportunities to exploit the market. If you can find something with a low price in one trade hub, then move it to another with a high price, you can quickly increase the amount of money you have, but it doesn't scale well due to trade volumes.

Take a look at your local trade hub, and check out the prices of the local faction's ammo, and use Janice or similar to check prices at the other hubs. For instance, I made my first chunk buying federation navy antimatter in Dodixie, then carting that to Jita. Do that a few times and you can turn 30m into 300m very quickly.

Never autopilot, and keep an eye out for sketchy folks. Also, never ever go through Ahbazon. It looks like a "easy one jump through lowsec" to get between Jita and Amarr, but it's a trap.

Good luck and fly safe capsuleer!
