We do not. We're a community organization composed of unpaid volunteers. I no longer offer private classes, nor does Jason Helmick. I'm not sure who else on the site might do so, but you're welcome to see who replies here.
Steven, I don't know if you have filled this need but I gave an advanced workshops for the IRS a couple of years ago at the Quest Software Headquarters. If you still have a need feel free to get in touch with me and we can discuss this the details.
Yes, I can do on-site. Where are you located. The workshop I did for the IRS was tailored to their needs and environment. Let me know what topics you want covered in your advanced training and I can put together a proposal.
