Blueprints channel, contracts.
Talos BPO, unresearched NPC price is 650 million, to give you a base. The more research you want, the higher the price will be

btw, ships aren't generally a good place to start with manufacturing.

Where should I start that will make me decent money per hour?

I wonder if street corner job would work:
- basically put killrights on you so others can pay to kill you again and again and again... I am sure sick bastards of EVE would pay for such service... but digressing:

For manufacturing, from personal experience (which might or might not be relevant :) ):
- T1 production is kinda pain, market is pretty much totally overflooded and any large-scale production will kill prices really fast (also you will need very high quality BPs and production skills)
- T1 ship production is pain^2 : to put it into perspective: you can produce like 80 Rokhs a day with single character with decent skills. Then you will cry in the corner when you realize blasted things have to reach market somehow and when they do, you will crash Rokh market and lose money; smaller ships are bit better, but still pain
- consumables might be of some profit (nanopaste and stuff), but don't expect stellar profit (and you will crash the market if you overdo it)
- capital modules can work, but haven't gone there yet - investments are huge, logistics is pain and I wonder how many of those are bought at regular basis
- T2 production > T1 production; basically take a look at how invention works, buy most of you what you need and produce T2 stuff. Most stuff will work here, but you will have to do some research (market research that is) to optimize; hint: more expensive stuff is not necessary more profitable, also beware of hidden pitfalls with blueprint runs, copy times, initial costs and stuff
- T2 ship production is not as bad as T1 ship production, but profitability is still not as great as one would expect, in my experience - the bigger the ship, the crappier the profit (not really intuitive, is it? ); my theory is that BPO owners dominate large T2 ship market (and fact that larger T2 ships are rarely used in PvP doesn't help)
- T2 capital modules might make you rich, but something is fishy there, so I have my doubts
- T3 production... hm... planning to try it at one point, likely better then T1, but again, something stinks about it

Also few things to keep in mind:
- EVE economy is overflooded with goods - it is simply fact, especially evident in T1 items; so most of stuff sits in someone's hangar somewhere - avoiding that happening to you is kinda... important
- hauling stuff around is something that people tend to ignore when planning manufacturing (talking about tritanium for those 80 rokhs)
- people can (and will) gank your transports full of stuff - it happens to everyone every once in a while, just count it in your expenses and profit equations
- keep in mind invention slots in places close to trade hubs can be choked, same goes for material research
