Need Help Migrating From ZenCart to Shopify by Cindy Kohnen

Hello,
We need help moving our current website (http://www.maggiescrochet.com) from Zen Cart 1.3.9 to Shopify. Our site has been selling crochet patterns and craft supplies for over 20 years and we have a solid customer base, but it is time for an update. We have been considering Cart 2 Cart (http://www.shopping-cart-migration.com/) to do the bulk of our migration with customers and products. We will be moving approximately 3,000 products and 50,000 customers. However, Cart 2 Cart will not create url redirects.

If we were to use Cart 2 Cart to import our products, images, and customers what would be your quote to create our url redirects. How much would you quote to migrate our entire site? Thank you for your help! We look forward to possibly working with you in the near future!
Please send quotes and details to cindy@maggiescrochet.com
