In string theory, one of the many vibrational states of the string corresponds to the graviton, a quantum mechanical particle that carries gravitational force. Thus string theory is a theory of quantum gravity.
Their average web application development cost is around $500K and their staff or contractors' salary is in the six figure plus range. Their proposals are usually based on a lot of fluff with the development rate ranging from $400 - $800 per hour. These types of companies focus on custom development.
To build an online store or application from scratch expect a team of 4 developers to spend at least 6 months designing, implementing, testing and launching it. At $50 per person per hour, working full time each month, the monthly cost is $32,000 per month. In this case you would pay $196,000 over six months. Development doesnât end: Development costs donât decrease after launching. They can actually increase.
