FAST DELIVERY, HIGH QUALITY
If you want your project delivered in a short amount of time, and also want it to be of high quality, then your web company will need to allocate more resources, such as staff overtime, to get your project completed fast at an exceptional quality.
These extra resources come at a cost, and your project will not be cheap.
HIGH QUALITY DESIGN AND CHEAP COST
If you want a high quality result at a lower than average cost, your web company will likely place your project at a lower priority than other clients that are paying their bills. So you can expect a longer time needed for development and delivery.
FAST DELIVERY AND CHEAP COST
If you want your project to be finished quickly and at a low cost, you can expect the quality of the work to be compromised. Your web company will not be able to dedicate the time and resources it takes to produce the best result.
