HI,
I have been working as a developer over last 5 year and expertise in php, wordpress customization, psd to html design, responsive web design and ecommerce store development in magento and data migration.
I have gone through your requirement and if you could provide me this task i will upgrade your Magento 1.6.* to 1.9.4 within 5 days.
Ready to start work right away.
Thanks for reading, I'm looking forward to hearing from you!
Thanks
