It all depends on what kind of standards and what you will be using them for. In basic (university) labs, maybe you can get away with making your own. In a government/regulatory lab, you must buy expensive certified standards, because there's a legal requirement to show traceability. Thankfully government labs usually have the budget for that.
Just remind your boss that the quality and trustability of results only go as far as how good your standards are. If you cut corners there, and quantitation is very important, it may bite you in the ass later on.
