Mimicking another Squarespace site exactly

I joined Squarespace because I stumbled upon a site that I wanted to format my site exactly like.

I found the theme, but it needs to be totally customized. This is where I'm struggling- trying to quickly figure out how to do so, quickly.

Is there anything you can recommend to help me to build my site faster and with more ease- knowing exactly what I want it to look like- with the example on hand? I feel like this would make it so easy for someone who knows what they are doing! Is there a tool to help with this? Anything! Thx.

Well, first thing is to post a link to the site you want to mimic and yours too. Now you may need to create a view only password for yours if you have not done that already. With those two things I bet we can give you a lot of hints and also let you know if the one you like has CSS code as well.
