Gentoo is free, open-source software. Its users provide assistance through the many venues of the Gentoo community. On occasion companies or individuals have specialized needs and are willing to hire someone to maintain or add additional functionality to their Gentoo systems.
As a service to the Gentoo community and to advance the use of Gentoo in the corporate sector, the Gentoo Foundation maintains a list of technical consultants ready to furnish professional support. The companies and individual consultants found in the list are not officially endorsed by the Gentoo Foundation.
The list of Gentoo technical consultants can be found here.
