clio 197 R26 megane conversion

hi,
I recently bought a Clio 197, a car that I have adored since the age of 15. Researching around the car I found multiple people discussing the engine conversion. Many people consider the conversion to be 'easy'. However, I have no previous knowledge of car mechanics and to be honest feel like a little bit of a fool.
I was hoping that the users of this forum would be able to advise me on what parts I would require to complete the conversion and if they knew of any reputable shops that would do the fitting of the engine.
I apologize in advance to anyone who sees my post as stupid.
Thanks Tom!
