To solve Email spam (From website to author), http 500 error in my website

I'm looking for an experienced coder to solve an email spam issue (from website to author) and a http 500 error on my website. The solution needed is a technical fix, so I'm hoping to find someone with the appropriate expertise to tackle this challenge. I don't have a preferred provider/developer, but someone with relevant experience in solving problems similar to mine. The scale of this project is small but I still expect quality results. If you feel you have the skillset and experience for this project, I'd love to hear from you!
