Advice from experience please😊

My fiancé and I are looking to buy land to build our home on and honestly no one in either of our families have done so before so I was just kind of asking for questions in general- like basically how to go about it, what some good prices are so we're not getting ripped off, do you find realitors to find your land? I just really can't find the wording because I know nothing about the process to really know what kind of questions to ask
