Integration between our wordpress website and Jobg8 software (XML snapshot feed)

We run a job board website (Hosted on wordpress & using the WP Job Manager plugin) and want to integrate our site with the Jobg8 software. The Jobg8 software basically send jobs to recruitment sites via XML Feed and allows users to apply for these jobs. Recruitment websites can forward their own jobs to the Jobg8 network to increase applications. We are using WordPress and WP Job Manager plugin. So if you have good knowledge of these then this will be the ideal job for you. It's pretty straightforward, however we require the feed to be able to make "amends" and "deletion" according to the requirements. Hence why popular WordPress XML plugins such as WP ALL Import will NOT work. I have attached a technical documentation from Jobg8 which specifies everything you need to know. PLEASE READ TECHNICAL DOCUMENTATION BEFORE BIDDING. We look forward to working with you!!!
