I would look for more gyms and compare the prices. Find a gym that has a mma team, after you get some amateur fights under your belt you can become a member of the team and train free of charge.
Look around for a gym that makes you feel comfortable and fits you.

The most important thing in any gym is the quality of instruction. Of almost equal importance is how you feel when you are in class, do you find it conducive to learning, do you have fun or do you feel like it's a job.
Never agree to lengthy contracts especially in Singapore.
It is hard to find good MMA gyms Singapore. There are not that many REAL instructors out there. It takes more than a guy who did karate and ju jitsu for a few years to be a good instructor. Most MMA schools aren't qualified in the arts they teach and some even just call them selves "MMA".
Professional means over 10 matches with competitors from long distances and diverse backgrounds. Some one who says he is the champ of small-town USA doesn't qualify. Some one with less than 6 years experience in anything doesn't qualify.
FIRST, do NOT sign any contracts. You might find a different gym you like better, you never know. In the event you do find a new gym or move or just don't want to go anymore you have to keep paying it until the contract is up. Just don't sign a contract. And- Honestly, I would avoid people who pressure you into buying or doing something.
