Don't pay extra for a 5 angle valve job. Industry standard is a 3 angle, and being charged more for a 5 angle is just not worth it. If you want to go nuts, you can find a machine shop that is tooled up with a Serdi and a radius cutter. They'll do a radius cut for the same price or minimally more than a 3 angle if you wish (usually). It takes them the same amount of effort, really.
If you can find rods already machined for 2g pistons for around $75, you'd probably be ahead. That's usually the minimum you'll end up paying just to have the small end bored to 22mm. Then you've got to pay for clipping the caps and honing the big ends back out to spec. Allow about $160 more in machine work to recondition rods, and fit pistons. Now you're at about $235, and that's considering the machine work to be fairly inexpensive. Go even more conservative, and take a shot saying it'd run you $200. Shot peening, cleaning.. will add more cost. You can buy Eagles for what.. about $300? (i think i paid 270 for mine) Problem there, is they're not press fit, you'd need pistons to match. Stock type pistons are all press fit. If you want to use ARP rod bolts.. there's a bunch more money in parts and work.
You can pick up a set of forged slugs for ~400, and put them on forged rods yourself, thereby saving on machine shop work there. To the tune of $60-$90 vs a press fit setup. That offsets the cost a little. They already come with ARP bolts.. possibly some more cost offset there as well.
I did the math on it all once, and found that i'd be far better off going with forged bottom end parts over a 1g/2g combo.
If you want to do it on the cheap, then just go with a stock bottom end. Guys have been making 400+ hp EASILY on stock for two decades now.
EDIT: It looks like you can buy 1g/2g combos assembled for around ~400 if you provide a good core set of rods. I'd still go with stock or forged, though. The cost difference is in the pistons, really. It's about $200-$300
