build a job board

I would like to build a website similar to [login to view URL] in wordpress. The job board is for a niche market and would need to send email alerts, allow candidates to apply via job board and confirm booking via job board. Rating enable for talent and manager both talent and managers will receive ratings (no comments). Free access for talent along with paid monthly access for more features and manager are free with full access to talent. I have a residence in mexico but payment will be in US dollars regardless of freelancer.com peso budget.
