Pricing page is a bit weird. If someone can pay $1000 they can probably pay $1500 a month. It sounds like its a service that can replace an in house designer so probably.

However pricing pages shouldn't have prices like that. Is there any way to change the model to have Free, $5, $30, Enterprise (call)?

Free gets customers but you don't need to mentally worry - there would need to be something that automates everything.

$5 is also automated, but maybe one of the features that you don't get "free" is available...

Maybe this is not really what you're going for though, so treat this comment as a half grain of salt.
