Hi,
Just would like to inform you that I am free on Saturdays and Sundays, so there is great chance that I will complete the assignment well within the due time.
I also have some experience of selling products online, so you can trust me with the job.
However, you have mentioned that you would like some feedback, I will have to ask you to please elaborate this for me a little bit so I can improve my communication with you if necessary.
Waiting for your kind response.
Regards,
Arsalan Pervez
