Dear friend
I am Joomla Developer.I have worked and had much deeply experience in migrating Joomla old version and VM 1.1 to Joomla 2.5 and VM2.0.26 . You can check these related jobs which I’ve done
About your jobs, I read through your description so I have more questions
+ How many products, joomla content and users you have?
+ We will migrate both VM Products, Order, Payment method, Coupon code or only product and orders?
+ Why you use K2 here? Old site you also used K2 Content?
What I guarantee
+ all Products, Content, SEO URL will be kept on new version
+ Layout is exact as old site.
+ Full document and guide after moving it to production site
+ Have warranty you at least in 1 month if have any problem
+ Good in English and ensure to reply you within 1 or max 2 hours
I really want to work with you on this project so looking forward to starting now. Thank you for your attention
Developer
