Beginner looking for advice buying macro camera!

[siliefly]

Hi all,
I am a jewellery designer/ maker and I am looking to buy my own camera and equipment to take my own photos as I am very interested about learning how to do it and think it will save me a lot of money in the long run to take my own product shots.
I have been researching a lot but I am also unsure of a lot! My budget is around €1500 in euros and I will be taking photos of small jewellery pieces that are not of reflective quality(look at Untitled Document for pictures taken of my work by other photographer!) I love these photos but the photographer has since gone out of business So as you can see the pieces are small and sometimes may be used for publications or posters so I need very high quality/ high resolution pictures.
To start I need a camera. I am thinking that I will need something that is at least 15 mega pixels? Would 15mp be sufficient?! I was looking at the canon EOS 50D ??
Then for the lens I was looking at the canon EF 100mm f/2.8L Macro IS USM This looks like an amazing lens but I am unsure if this is right? I do want to buy the right equipment that will last me.
Then for the flash: when researching the Canon Macro Ring Lite KIT MR-14EX 100mm 60mm 50mm Lens was recommended but this is pretty pricey I think, I wanted to spend the bulk of my money on the lens as this is the most important? I then read that a Canon Speedlite 270EX would be sufficient for flash if I bounced it off an overhead white wall or something???
Do I have this all right? I want to make sure I get the proper stuff to set up with so that is why I am asking for your help in this forum!!!

Thank you very much in advance ☺

Eily
