Web Design,Programming,SEO

I am in the process of looking to hire a web designer, who thinks outside of the box. At the same time, I want to ensure that the site is being designed for immediate search engine optimization. I am starting an intertet matchmaking company, unlike all the other online dating services. I will probably have it all hosted. I would need help with programming too. I do need a really professional website, I am ready to go, talking with funder Tuesday and need some idea as to what the ballpark maimum-maximum cost would be, for as much as you can do. Please let me have some estimate at your earliest convenience. How long would it take to get the website up and how long would you think it would take for the website to start receiving hits from the optimization? Thank you for your time, I look forward to hearing from you. Yvette
