Website Development Needed

I am a business owner looking to have a website developed. The domain name has been reserved, the pages have been layed out as to how I want them to appear, and all text including meta tags, descriptions, keywords, etc has been completed for each page. The website is adult in nature, but is more along the lines of a dating type site than a theme site. It will be a pay site with a members only area, and members will have the ability to post their own picture w/ their screen name. It will need to be readable and optimized for not only english, but also spanish, japanese, german, and french. The site will have in the area of 15-20 pages including a member login page, join now page, browse members page (by country, state, city, etc), browse events page, and an area for members to post their own, as well as search for upcoming events (also by state, country, etc). I believe this is a complete description of our needs but if you have any questions, let me know. I am trying to give as many details as possible without giving away the entire concept as I have not seen anything like this on the web. Thank you in advance!
