531148 Art/Event/Community website needs Drupal expert

Hi, I am the co-founder of an online site for contemporary art about news, events and opportunities in Southeast Asia. This has been made on Drupal. I am looking to see if you can help me: 1. get rid of the bugs on the site (since it has been transferred to a new hosting system, it has encountered bugs eg. toolbar on text/message does not show up) 2. Improve my events section (events that are current should be on top, events that had passed should automatically be unpublished) 3. Install a section where I can upload an .mp3 and be utilized by the public as podcasts 4. be able to share the events and articles on facebook. 5. pages on listings page should all appear (sometimes it doesnt). Let me know if this is something you can help me with. Thanks and looking forward to hearing from you.
