Help with DynDNS – need to make my home’s server visible from the Internet by lupesantiago

All I need is somebody to help me set up whatever I need to set up to make my website visible from the Internet. The site is visible from my network at 192.168.0.13, but I do not know, and the instructions on how to do it are a NIGHTMARE, how to make it visible from the outside… (Budget: $30-$250 USD, Jobs: DNS, Linux, System Admin)
