nGrinder is the open source project which is free to use now and forever. We're developing nGrinder to make the web more stable and reliable. However there might be some organizations who want to deploy nGrinder as their base development infrastructure. For these guys, we can provide some professional services to facilitate the performance centric culture in your organization. This may include followings.
Price? We don't have a such a thing yet. It just depends on how big your requests are. If you're a big committer for nGrinder, we're willing to do without charge.
If not, we might charge you according to the amount of the time we put on to solve your requests. Please contact to ngrinder.nhn at gmail.com if you're interested in.
