Ongoing edits to Wordpress Site

Need someone to make various changes on a task by task basis. Site is around 15 pages. Begining tasks are: From .psd file--- change background color for entire site(CSS) Graphic changes navigation and layout changes - Larger/Bolder fonts sitewide (need recommendation) - New Nav Bar throughout (see .psd) - remove page - New Home page copy ( will provide) - New Home page video (Center) ( New video to post on YouTube and link to site.) These are not time-consuming and the site is built but I need someone to take care of these edits. Please provide previous Wordpress projects. I need a Wordpress/SEO expert to help with site enhancements and SEO efforts as well later.
