Hello,
I hope you are doing well. I would like to offer my services to you for a continued freelance arrangement because I believe my past experience with HTML, CSS and Javascript can come in handy.
I have read the document and i can complete the job for $18 + freelancer charges to you. Hopefully i can complete the tasks in 6 to 8 hours. This is basic work which is why it should not take as long as 36 hours. Do share if there is anything else you want to discuss.
Regards,
Sarmad.
