I need a professional logo

Information for the business: We are a specialist dog handling company
Type of logo: Emblem, Character
Brand name/slogan in logo: the specialist dog house
Ideas for the visual style: We are a specialist professional dog handling company. We provide security/search services to our clients. This can be anything from searching large football stadiums for flares or drugs to specialist onsite security services with our dogs.
Things to avoid: nothing gimicky - our clients are large football associations and we also work with the police
Preferred colors: as long as we dont clash with emergency services
Where the design will be used: print/web/advertising/marketing
Extra notes: Please quote for a logo design plus provide relevant samples of other logos you have designed. This needs to be done ASAP. Thank you!
