Squarespace design tweaking

I have my website nearly up and running. I require some fine tuning.

I'd like a line that runs under the logo across the whole top of the site. I would like this same line to be at the bottom of the page also.

A search box top right then the buttons to be to the left of that.

Custom fonts

Instructions on the easiest way to add a new work project.

I want somebody who has good knowledge and examples of Squarespace on their portfolio as their is a risk of a novice loosing site and / or code.


Please give loose quotes as I understand this brief needs to be explained in full. I have screenshots of exactly what I'd like.

Here is the site as it currently is - www.richardpayne.squarespace.com
