Montering af anhængertræk Vordingborg

Hi.
I have a car Opel Agilla B 2008 and I need ,,Montering af fast anhængertræk" or ,,svingbart anhængertræk"" propably ,,Montering na 7 pol stik". I rent a house with big garden so I need to have a towbar installed in my car to rent a trailer and haul away all the mess. What product can you offer me? What would be the cost of the product with installation in your car repair shop? How much time do you need for assembly? I please send me offer on my email [email protected] I live post code 4760.
Regards
Monica
