If your main service is installation and service your site is most likely suitable for the Regional part of the ODP at the locality where your company is based.  The site is only eligible here if it offers installation and service in more than one country.

Sites specializing in online sales of equipment, parts and supplies to the paint booth industry may be listed here, but those also selling consumer products should be suggested to the most appropriate sub-category of the Shopping tree instead. Those sites selling products only locally or by visiting their premises may only be listed in the locality category within Regional.
