Four possibilities

Which law firm - if any - wrote these contracts which are under investigation by the Public Ministry?

Four possibilities occurred to me:

a) Fourhouses
b) Quatremaisons
c) Cuatrecasas
d) Quatro Casas

And which lawyer did it?

Again, four possibilities occurred to me:

i) Paulinho
ii) Basquinho
iii) Dr. Abides
iv) Quequé dos Protocolos
