Hello Sir,
I've read your project description and I understand that you're looking for someone to modify your PHP script to bulk upload. Such job is my daily practice, and I'm confident to say that I can complete this job. Not only I'll complete the job, I'll deliver high and strict coding quality with proper documentation.
My name is Duc Nguyen, and I'm a Senior PHP Developer with more than 5 years experience working with PHP, MySQL, jQuery, etc. Also, I'm a fulltime freelancer, so I can start the job right away.
Hope to hear from you soon.
Best regards.
