We are a San Diego web-development services company offering a flexible model for project cost calculation. We have hourly rates for web development engineers and our mix of local and remote resources (not freelancers!) from our R&D offices in Eastern Europe and worldwide. Your specific project estimate depends on many factors, including the scale of your web application and the complexity of your project. A ballpark estimate for a small- to a medium-scale project would be $60,000-90,000 USD, on average; however, there are too many aspects to consider here. Contact us for details.
