Need to Find a Theme for a Market Place for Law

I am looking for a theme for a marketplace such as fiverr, but for people to find legal service providers specifically. The user must be able to find a freelance lawyer and purchase gigs from lawyers who are listed as suppliers on the site. The consumer must be able to rate and review the service provider. It must work very similar to fiverr but it must be specifically for the legal industry…Can any developer/author point me in the right direction please…A theme of this nature in wordpress would be great.
