Need occasional assistance with backend management -- pay by the hour

"I'm the end user of a small website (see www.billherring.info) that runs on drupal 6.6.  I'm in need of a cost-effective backend manager to handle occasional code writing and other troubleshooting issues as they arise, such as technical questions I may have from time to time. The person I relied upon for these services is no longer available. I don't anticipate needing much help but need someone in my corner when I do. I'm a sane, reasonable customer without unrealistic expectations. It seems like an hourly rate is best. We'll probably both be able to determine how well this works after the first one or two occasions. I've seen lots of postings here that go unanswered so I'm not hopeful, but hopefully somebody will see this and respond in a way that helps us both.
