Help with choosing a Live Chat Support Software

Does anyone know of any Live Chat Software that I can use, what I mean is Live chat software and/or live chat service where they do the customer service, I’m looking to outsource my customer service to a 24 hour live chat operator because they are cheaper than paying for staff myself, I found one website that was recommended to me called live247support dot com This site seems to offer Support at a really good price. And id much rather go with a recommendation that just simply randomly searching on Google for it, If anyone in this forum is using a service like this, please let me know what they are like and then I can make a final decision who to use.
Thanks!
