Dating Site

I purchased a website and am looking for someone who can upgrade it for me, if that is possible. I am concentrating on an international niche, because it is international, I would like the site to support a couple of other languages besides English, mainly french, and Spanish, but I think this can be created later on. I would like to turn the site into a dating portal, and the things I really want the site to have are an Internal Msg. System, Who's Online/ Last Login, Profiles that has been viewed the most, Bookmark Profiles,Ignore Profiles, I.M., Add/Edit/Delete Profile, Flirting, events page, message board, and newsletter, Reminder, User of the day/week/month, type of membership(silver/gold/patinum) must accept paypal for membership to site plus a dramtic, eye catching header. The website already has most of these options, all but the IM, message board, events page, and flirting capabilities, I think. I want this to be a place where people can come and meet others, for dating and romance, the website will further be expanded in the coming months to include a marriage service, so expansion must be possible in your design. I am looking to get the site completed by the end of this month, so that I can start the marketing and advertising efforts, so there is a time urgency. I would rather have you come up with a quote, but I am looking to spend around $500 dollars for the project, but this number may be negotiable. Please take a look at the current site at [login to view URL], and see if the changes I want will be possible, if so let me know your quote as well as the time table in which you believe the project can be accomplished. Thank you and I look forward to your reply.
