build wordpress child theme

I want to build a wordpress child theme for clients. I was thinking child of the theme "suffusion" or "atahualpa" but I am open to suggestions on parent theme. This child theme should be named "nettsett 1" I have made an illustration of the page in photoshop. I would like two columns, header area, one column/widget area above footer and a footer. All of these elements shold be adjustable with the usual options for background color, fonts, width of the page. There must also be an option for widget areas, one in each of the two columns. I am not experienced in programming, so I am looking for someone who can make the best possible solutions for flexibility. The wordpress dashboard should be customized through the child theme [login to view URL] file, so that the client doesn't have to relate to all the possibilities of the parent theme. Is there a possibility for creating one wordpress admin panel for me, where I can see all options belonging to the parent theme and child theme? And then one wordpress admin panel for the client, with fewer options? ## Deliverables I need an expert on wordpress and someone who is honest and creative. Because I don't know that much about programming, I need someone with their own ideas on how to solve a problem. If the hired worker does a good job, I have many projects in the future where I will need similar help. Please view the jpg image of the sketch for the finished page. I have only defined areas that should be present, the measurements of each area should be adjustable through the wordpress dashboard.
