    I was buying a business and was going to invest a huge sum of money .....I needed help with figuring out the background of the seller because i didn't want to get into any fraud kind of situations. So I contacted Investigation Hotline. Mitchell gets on your case right away. He is very easy to talk to...and his results are instant. He walks you through the process step by step for budget conscious clients and keeps you up to date as often as necessary about what information he has acquired. Great person to hire and good person to get advice from. He is only a phone call away and I would definitely use him again.

    Man, is Mitchell amazing. He is a wizard. I contacted Investigation Hotline Canada and Mitchell was not only understanding of the situation, but him and his team had an answer for me in less than 12 hours, and he then proceeded to coach me through the situation for free. I love working with people who exceed above and beyond expectations. Can't wait to work with you again, this level of professionalism is incredible. I'm going to refer everyone I know to you. Trust Mitchell and his team with your secrets and your money, I can't rave about them enough. Thank you
