Price depends on design and brand. Ferruni will be about 80/piece 2x4', Niro sligtly more. But can also wait for sales, usually discount 20-30%.
Recent homedec also had a good deal from Lorenza Ceramica. 2x4" for 30-50/piece. But quality unknown for this brand. But the shop also carry lotsa mapei products.

1 piece of 2x4 is more expensive than 2 pieces 2x2. Installation charges also higher.

For walls, this is expensive and not many tilers willing to do. Dont expect them to give you psf price. You can just ask your ferruni for tiler contact. I would advise getting experienced chinese tilers. You wont want these expensive tiles to fall off after a few years. And use at least C2TE or better glue.

If for bathroom of 50sf and 9' walls, labour (exclude hacking old tiles) + screeding (waterproofing not included) + material (exclude tiles) will be about +/-RM5K(lumpsum).

"market rate" nowadays has quite a widerange, depending on location also. For KL,

Chinese only tilers ate top end, known for good quality work and wont use cheap glue. Tiles straight, gap even, installed flat, substrate mixed well and covered 100% of backside. Willing to do 45degree mitered edge. Bring their own material, equiptment. For basic 2x2 tiles for floor, expect rm8/sf up.

Cheapest is get those banglas/Indons to kerja Kong. Day rate about rm120/pax nowadays. You need to buy all material, equiptment, arrange delivery and monitor process yourself. The use whatever material you supply. Can work slow, as its day rate. Workmanship depends on experience level. And prone to fly off next day if they get other jobs, leaving your unfinished job hanging.

In between are all mixtures of chinese supervisor with foreign labourers or foreign labourers only specialised in tiling (eg some pakistani) or others.

Best pricing for tiles comes during sale. whichever the company. Merdeka and year end sale usually the best for tiles, but most tile companies schedule sale to coincide with major celebration like CNY and Hari Raya. But have to get what is on sale, usually clearance items.

Even companies like Niro/Creative labs can have some of their spanish-made tiles at 75% off sometimes.

Some batches like project extras also under clearance most of time.

Or weird/unpopular sizes like 1000x1000mm, 900x900mm, 750x750mm etc are usually on sale clearance.

But one advise is to get the best tile you can afford, as nowadays the cost of tiling is usually more expensive than the tiles itself.
