Hiring Unity Developer

Hi guys,

First and foremost, I do apologize if this isn't the correct place to ask this question as I understand this is a community for developers.

Do anyone know a good source to review and hire an actual unity developer to modify an existing asset that I'm using for a word game? I don't imagine the modifications I want to take long and I'm looking for a cost effective developer to make the changes to ensure that my optimization and device compatibility requirements are met. Thanks.
