WP Theme Customization - THE7 - repost

Hi There, I have "THE7" wordpress theme. As default option in theme settings - it only comes with Wide Screen OR Box layout. Please can someone help me? 1) I would like a way to have either Wide Screen OR Box Layout on a Per Page and Per Post basis. I find the default box layout at 1360px is too wide. I would want option to choose the box size I want, 1040, 960. Background image + colors to function as normal. Every part of theme would need to be carefully checked so it all works together. Keep everything the same... 2) I want switches (light blue) like ON/OFF 3) Would need all changes documented with code and files adjusted 4) Would need your help to move site from test server to main server, and ensure all changes will not be lost during theme up-date. Please let me know what you can do. Small budget but I really need this done quickly. If you know what you are doing should only take a few hours. Please help. We can chat live or via email. Thank you so much...looking forward to having you help.
