Assistance before go live with a Magento shop

I've a shop on virtuemart 1.1.9 which is migrated partially on a magento platform (i'll finish the migration in the next few days with cart2cart) Magento website is almost ready, but there are few fixes needed in design and functionality. Also i will need to mantain the old sef urls once magento is live and to import wholesale prices and delivery time for each product. I need someone who can start immediately and finish the job as soon as cart2cart has finished the migration. Please DO NOT BID if you are not expert because the shop is live, is my job and is not a game for me. Thanks
