You've gotten a lot of good responses while I was writing my own. There's some repetition here of what others have said. If there's any contradiction, go with what SL or THP have to say. That said, here's my response:
If you want to grind everything together, seeds included, a commercial food processor might work for you. Both Hobart and Robot Coupe make such things.

Both make high capacity floor models, too:

However, it's possible none of those will grind the seeds as finely as you might want, not to mention any negative impact on flavor from the seeds. I've used a vertical grinder, that I can't recall the make right now, that would do the job, but it was such a pain to disassemble, clean, and sterilize before and after every use, that I started using a Robot Coupe immersion blender instead. One of these, I think:

That, of course, also won't necessarily grind the seeds as much as desired. I stem and seed a lot of the superhots I use by hand, but for high volume production or something like jalapeños, I cut them in half (one black-hearted pepper can ruin a whole batch of product), steam them to softness, then run them through an electric tomato finisher, variously called finishers, mills, squeezers.

Several manufacturers make capable products. My advice is to get the biggest horsepower motor you can afford. The one I use is a discontinued model, but is similar to this one.

I've only used it to remove the seeds from jalapeños, but it worked okay for that. I had to run the seed/pulp waste through a few times to minimize loss of pulp. After about the third or fourth time, it started shearing off little bits from the edges of the seeds that looked like tiny little worms in the pulp. Stopping the recycling one run through earlier got rid of that problem.
Somewhere I have the numbers for the pulp to waste ratio for the electric finisher vs. doing it by hand. Obviously, it's not as good as hand processed on that number alone, but when you factor in the time savings, it becomes a no-brainer in favor of the power tool.
