Honestly speaking, it is hard to find committed 10+ years of experience developer, because whoever will have 10+ years of experience, he can hardly stick at one place but I would be happy to tell you that one of my main developer is with our Company since many years, I can assign him to you, so you can work with him directly on any of your PHP projects. Just so you know, he is also a really good team lead, project manager and developer, because he worked on many platforms, OpenSource, new technologies etc. After all he spent his 10 years in development.
