Try to fin solutions for digital magazine

[AlexNiko]

Hello!
My name is Alex. I'm photographer. Me and my friend want to produce digital photo magazine for ipad. We bough Adobe DPS Single edition to test what we can. Now we try to find some solution more cheaper than Adobe DPS prof. What we need:

Buil app that support subscription (like Time or NewYorker). Spend less money than Adobe want ))). I would be grateful for answers.

Alex.
