Here are some links to landing pages I have worked on.
I have experience in building lading pages using Leadpages and Mailchimp which require you to subscribe to costly annual subscriptions or greatly reduce the available features.
My setup means that I can create and host your page for a fixed cost, bypassing these expensive landing page building subscriptions, while offering a huge host of features.
They can be as simple or detailed as you need them to be.
Each one is tailor-made to fit your requirements and your branding.
