There are a few reasons why you might want to hire a Microsoft Infopath developer. First, if you need someone to develop custom Infopath forms or templates, then a developer with Infopath experience would be ideal. Secondly, if you need someone to integrate Infopath with other Microsoft products (such as Sharepoint), then again, an Infopath developer would be ideal. Finally, if you simply need someone who is familiar with the product and can help train your staff on how to use it effectively, then a Microsoft Infopath developer would be a good choice.
