Hello what kind of portfolio are we talking about? I need more information of your business so I can deliver a proper product.
Please do not buy from copy/pasted bid's because they only care about quantity and hardly ever provide a satisfactory product and customer service.
If you get lucky enough they will speak English and really understand what you need.
We are new to Freelancer.com, but we are 8 years on the market giving your needs the full ride into the software design process, therefore offering a very price final product and we have the best customer service you may need.
Our Kindest Regards,
KR Team.
