Let's take the three questions separately and respond according to your numerology profile and general life principles.

I want to know if construction business is suitable for me?

With a birth date number 8, most businesses would be suitable for you. A construction business is especially suitable. You'll find satisfaction building things with good workmanship that will last a long time.

With a 3 name number, you're likely to have at least some opportunities for your own creative expression in the things you build.

To what extent will I be successful?

It depends entirely on you. If you do the things that make you successful, you will be successful. Success takes action to achieve what you are aiming for. It won't happen just because someone says it will; it takes personal activity, getting things done, doing the steps required to achieve the target that is deemed to be success.

If you desire a foretelling regarding your success, perhaps a tarot reader or psychic can help. Numerology calculations don't determine a person's success or lack thereof.

What should be the name for my company?

It should be a name you are comfortable with, that resonates well in the region where the company is going to operate, and that is compatible with the type of construction the company will be doing.
