I've set up two WordPress job boards for myself so I know how to provide a jobs board that is:
a) SEO friendly (important)
b) processes any credit card with Stripe
c) mobile responsive
involving editing themes / child themes, customising logo / colors, implementing plugins and providing eCommerce solutions with Stripe secure credit card payments
Check out my two websites reservoirengineerjobs.com and oilandgasjobs.io which both have child themes running
Can get your site up and running in 3-7 days.
Happy to Skype out a solution for...
