Dear Mr./Mrs.,
My motto is quality and not quantity; therefore, in case you accept my bid, I would focus on your project with the aim of getting your 100% satisfaction, and your 5-star review. And it is also why I would not offer "in 3-4 days". Perhaps, it can be finished in 3-4 days, but I don't want to promise without analyzing the webpage, since I want to accomplish what I promise.
Of course I am interested in a long-term relation.
I would need access to the different files with html, js,, css code, and images.
Thank you in advance for your attention,
yours sincerely,
Javier
