It is much quicker, easier and cheaper to buy transmitter and receiver modules than to make them with individual parts. It depends on the radio regulations in your country, cheap 433MHz modules can be used in most countrys.

In small quantitys buying the RF parts for a transmitter will probably cost more than a pair of ready made modules.
