No need to, the nurse bees will produce it.
I've never bought royal jelly, but would suspect that it would be dried or processed in some way to preserve it, and no longer suitable for bees.
Some good info on Queen rearing:http://www.dpi.nsw.gov.au/__data/assets/pdf_file/0003/252129/Rearing-queen-bees.pdf
Also google cloake board for a simplified version of cell finishing and jenter kit for no graft queen rearing.
Good luck with it, let us know how you go. I am planning on having a crack at it next year.
