Problem is, Apple makes doing that a complete nightmare. I wouldn't even begin to know how to get others credentials and provisioning profiles onto my mac to publish for them. It was such a pain in the butt when I did it for just myself, and now that I have it all setup and configured, I would be scared to mess with it :).
I do understand the frustration though, but if you plan on creating games of iOS, then I think it's better to work though it and get yourself all setup. Took me a few days with lots of google searches, but in the end it was worth it. I went the cheapest route I could.
1. Mac Mini $599(Applied for an apple Barclaycard Credit Card when I purchase it and got 0 percent for a year). Paid it off in 6 months.
2. Ipod Touch 8gb from Ebay $100
3. Dev Account from Apple $99 per year.
4. Account on Appcod.es for keyword SEO. $14.95 a month.
It's a bit of investment, but it all paid for itself rather quickly.
