I wouldn't want to compete with Leadpages. Their tool has it all: lots and lots of flexible, customizable templates, great integrations and an unbeatable price, starting at $25/month.
You can even use their leadbox popup forms on your own website and collect leads into your Leadpages account. They do a lot of coaching, webinars and workshops so beginners will be taken care of.
They will also create Facebook Ads straight from your landing page text, you just tweak it and you're ready to go.
There is a free trial available but a credit card is required.
