Hello and welcome to Android Forums. Hopefully I can help you with your problem.
First off, you will probably need to root your device if you have not already done so. If rooted, I would try the Play store and look for Wifi Tether for Root users. That is usually a good app to try for many users. It's pretty easy to set up too. There are several other apps on the market too but most require that your device be rooted.
Another choice you have, and this is the one I recommend, is to join Android Forums and check your device's section. If there is a way to make a hot spot work for your device, that's where you'll find the information you seek.
