Good morning Fathima,
Let me start off by saying it will not be easy !!!
Starting a business will take time,effort,commitment and passion.
You will feel like quitting but don't keep heading strong and work hard.
In order to Succeed and beat your competitors you really need to market and advertise your business by Online and offline. In today's world we use Facebook,twitter,Instagram and lets not forget Qatar Living use these as your platform and sell your business.
In Addition, remember to have a good brand identity. Brand identity is what people will judge you on before even knowing about your service or product, If your brand Identity does not look aesthetically pleasing to the client they will not be motivated to invest in it ( CONTACT ME I CAN HELP YOU IN THIS PART AS I AM A FREE LANCE GRAPHIC DESIGNER)

Lastly, GOOOD LUCCKK :D
