is there anywhere I can look that wouldn't cost a lot to find people in specific areas do you know?
It's hard to answer that without knowing which areas and what time period. But whatever method you use to find possible relatives,
never believe anything you find on the internet unless and until you have verified it by looking at the original document. There are thousands of family trees out there, and you have no way of knowing whether they have been properly researched, or are a complete tissue of fantasy.
There's some advice on getting started at
http://www.scotlandspeople.gov.uk/Content/Help/index.aspx?r=551&1 (you may have to register, but registration is free) and this site is the only source of digitised images of the statutory registers of birth death and marriage from 1885 onwards. You cannot get that information without either you or someone else paying something for it, but there are ways of keeping the cost down.
The important things is to start with yourself, your parents and your grandparents. Wrtite down what you know, or get a genealogy program - there are plenty available - and record the information systematically. Ask older family members and record what they tell you. Once you have exhausted that, your are ready to start tackling the actual records.
Once you get back 100-odd years, it gets easier, because there are more online indexes and transcriptions you can use as guides and pointers. But don't expect to be able to do everything for free, because that's not how it is.
