Dating site with Dating directory

Dating web-site, Similar to 'friendfinder' with similar record keeping capabilities to assist accountant with financial,marketing records, #of members in certain categories...). It will also have a date making sectionlike a escort service but 6x less involved. Member write in when they want a date, the time, e.t.c than other other members can respond vial e-mail. Members will not pay for dates because it will not be an escort service. I'm looking have a basic 'dating directory' with it. Categories will be regular text ads with links or banner ads. Order of ad listing will be based on who pays what amount. Person who pays the most will be at the top. Need ideas as to how I can better set the directory section of the site. I will also need 2 banners created.
