Hello Manish Khemani
We have helped many clients in building custom Guided Marketo Landing Pages. We can help you with both the template builder and a Master email template. Our Master template is an ideal solution for Marketo users who want a single, all-in-one template that could be used for all of your marketing activities. We have a base version available - that you can purchase without any customization. Also, we can work on a significant amount of customization - including advanced techniques to display multiple variations of a module based on screen size (not just responsive design). And of course to make everything align with your brand guidelines. Please follow me so that we can discuss further.
