You can get started with 2Checkout or PayPal, get some traction and include multiple gateway support when you are ready to get a merchant account. You could also use a good subscription billing abstraction service to use like ours who do not charge minimums. ;)

Your customer card info stays with PayPal or 2CO and if you are building a business focused product that requires beta with fewer customers initially, you could request them to migrate over in the interim if that is possible.

The place I come from most startups are at a disadvantage with gateways demanding huge upfront fees or yearly minimums and this is one approach that generally works. See Deskaway or VisualWebsiteOptimizer that have built their entire business around 2CO or a combination of 2CO & a local gateway.

From your signup forms, it seems like you guys are limited to the US as well...?

2 US gateways integrated currently & launching with 2CO. PayPal support is coming soon.

EDIT: 2CO accepts & settles in DKK/EUR. http://www.2checkout.com/international-payments/
