I wouldn't see there being problem mentioning that you own one. I don't think that I would recommend my own service without mentioning that it was mine, and offering alternatives. I'm not sure that I would really want to offer some services from side businesses. There is a possibility that the company might end up expecting a higher level of service than was standard, since they were employing you. That probable wouldn't cause problems since it is just a domain register and the company just needs a few domains. Also, a few people might question your judgement on your recommendation with the conflict of interest. I wouldn't really be worried losing the few dollars to competitors.
