Dynamic WordPress live JSON feed

I'm looking for someone to work on a WordPress site for me to import JSON into a series of custom post types. The JSON feed will need to be split into at least 4 custom post types, that contain Advanced Custom Fields that must be populated. This feed will need to be live, or near live i.e. refresh every 10 mins. This import will be continuous and ongoing process so this is not a one off task. The code / plugin must be robust to continue to work without supervision and input on a daily basis. The JSON feed will be behind a basic level of authentication which will need to be worked with. I am happy for this to be a plugin that you install and configure OR custom code, but the costs should be kept to a minimum. I am looking for someone to proceed with this within the next 3-5 days. Thanks #wordpress #json #advancedcustomfields
