Magento Commerce Modifications

Need to make some slight modifications to how magento display product options. Instead of just showing the product options from a drop down we need it to also show a preview thumbnail for each option. This website is for custom made clothing accessories and it needs to show pictures of different materials as customer is selecting options. please bid your hourly price. Winner bidder needs to be familiar with magento commerce and also SVN since all the code is in a SVN repository. Please let me know if you any Similar Past Experience and References Please Bid your Hourly Rate for 1-2 weeks of work Thanks PB
