Hello Sir,
I've read your project description carefully, and I understand that you need someone to make some changes to your current Magento website. You've also said to read the attached file, but I couldn't find it. But such job is my daily practice, and I'm confident to say that I can complete this job.
My name is Duc Nguyen, and I'm Senior PHP Developer, with more than 5 years experience working with PHP, MySQL, jQuery, Wordpress, Magento, Joomla, Yii, etc. Also, I'm a fulltime freelancer, so I can start any job right away.
If you have any questions, don't refrain to ask, I'm happy to answer.
Hope to hear from you soon and to work with you.
Best regards.
