Does anyone know of a decent Company, in the London area, that can help me with Landing Page and Form design - I need to build a Subscription Centre too, so maybe some knowledge of Marketo programs etc would also be useful. If not an Agency, what advice would you give?
Have you tried Knak and Unbounce?
If you play around with the templates enough you can pretty much get the landing pages to look however you want.
And Knak integrates directly with Marketo so that is a plus.
Also, you should probably post this in job opportunities as it will get more exposure there.
