When a website designer has given you a quote for designing the website then that is just the quote for designing the website. PERIOD. This does not mean the web designer will work for you for a period of 3-6 months finishing your website according to your timing, convenience and liking until you are 100% satisfied (unless of course the website designer has told you that he will finish your site in 3-6 months and will work until you are 100% satisfied).
