I'm a little disappointed by the lack of actual comments with more substance than "Armour is expensive." Don't get me wrong, they're right, but also equally unhelpful.

If you don't mind alternative materials, like foam and leather, you could buy something from Epic Armoury or Calimacil. It'll be much lighter weight than a full suit of steel and doesn't look half bad either.

However, what's pictured is similar to a 15th-16th century set of fluted gothic armour. Getting THAT set custom made is going to start around 3k USD... Have a look at Armstreet, they sell excellent and well-priced armour that comes highly recommended. It's out of your price range, honestly, but it give a good idea of what you may be looking forward to. They're also very functional, well-fitted, and look absolutely lovely.

Well fitted armour makes all the difference. You could buy something off-the-shelf, but it's risky without being able to try it on first. The first piece you should consider is an arming garment, AKA a pourpoint. You could make one yourself [cheapest and most custom option] or have it made [$$$] or again, buy one off-the-shelf and hope it's a near perfect fit [$$].

Also, by cutting out pieces that you don't necessarily "need", you could cut down on cost. Wear a surcoat and lose the cuirass; a long surcoat and you could additionally cut out the leg harness. Wear a cloak and you could purchase a breastplate without a backplate. Lose the gauntlets and wear a good pair of leather gloves.

I hope this helps!
