161125 Joomla Tweaks required

Hi, My website artfromsteel DOT com has some design problems: 1) The header image is 900 pixels and therefore displays incorrectly on 800 pixel screens. I plan to revise this header image in the next 2 days but will need help resizing the site so that it universally work with 800X600 resolution displays - Maybe a relative width would be most practical? 2) There are various layout issues in different resolutions 3) I don't think the CSS is written efficiently and the homepage seems too large when loading. 4) I'd like the installed VirtueMart module to display three products per column rather than 4. 5) I wil lbe revising the contents ogf the homepage. Feedback / suggestions will be appreciated to make it look appealing. _____________ This is not a design project so please don't bid and tell me you will be providing new graphics. I want people experienced with Joomla. Please don't bid if you have not used it extensively. When bidding please prove to me that you've looked at my site and that you understand what's required. Thank you Martin
