Thanks Jane, that's the info I was looking for. I have done alot of research on the Internet, looked at before and after photos etc. I understand about the risks and have taken that into consideration. Also, that they may not look the way you want them to and then it's too late. I have seen some bad jobs out there in photos.
It's something I've been thinking about but not to the point of actually going for a consultation. Not a decision to be taken lightly.
