Hi bro, another way is to buy 2nd hand nano tank and equipments from buy-sell forum here.
You would need good lighting. QH, price wise not really the best.
For starting, this website provides useful info:

I started my first reef tank 6 months ago.
I used live rock, live sands, and Nutrafin cycle bacteria (so, I didn't need to cycle my tank).
Marine live stocks mostly available at pasir Ris farm way, lim chu kang.
If you are living in central area, there is Sea Life at Balestier near Quality Hotel, there is Aquamarine around Tai Seng and Wong Loy Kee at China Town.
