CSS Styled form with drop down list

Hi there, I am using the Optimizepress theme for wordpress. I am trying to add a stylized mobile friendly form. However; at the moment they only support text fields on all our opt-in forms. I need someone to take my form code (from [login to view URL]) and add css styling to it so it matches the same exact look and workings of the optimize press form but will include drop down fields. This new code can then be pasted into the HTML element on the LiveEditor pages in optimize press. [login to view URL] is the page with the form. I just want to add a drop down field to this. but you will need to create a css style sheet to make it look the same. I will provide you with the form code that 1 shop provided me.
