It's a fair question. The per-solve prices you see quoted (a dollar or three per 1,000) feel like something you could undercut with a weekend of code. Sometimes you can. But the sticker price of a solving service isn't really what you're comparing against — you're comparing against the fully-loaded cost of owning the problem forever.
