Dear sir,
I have been in this industry for 5 years and such jobs are my daily practice.
I can assure you that if you work with me once, you will always work with me for these kind of projects.
I download your file and its very easy for me.
This is my first time on this site and hence you can see that I do not have any ratings/testimonials to show you.
