Hiring a PHP developer to help finish up a website - Please kindly have Frontend experience :)

This tasks involves a tiny bit of wordpress, very simple (I just became a father, so my coding time is limited): Tasks I'm using either Gamipress or myCred: - User uses points from the above plugin to "buy" an API key from my licensing system: This tasks will just be an AJAX request on a function that: 1 ) Deducts points from the user's balance 2 ) Generates the License Key 3 ) Sets a value so they can see the license key whenever they come to the page 4 ) Checks to see if the key is expired when it's loaded, so they can buy it again the next month The next task involves frontend design: - I need help cleaning up CSS to match my HTML template. There's going to be a lot of elements from wordpress plugins that require some CSS clean up (they're previously generated from default themes of the plugin). I have a $100-150 budget per task depending on your quickness to get everything running. Thank you for your time.
