We bill hourly in USD: $15-$30/hr for web, ASP.NET, CMS, SaaS, cloud and API work; $20-$35/hr for .NET MAUI and Flutter mobile apps; $20-$30/hr for AI integration such as RAG and chatbots; and $10-$15/hr for SEO, content writing and digital marketing. Custom web development is quoted on inquiry after a short discovery call.

Both. Well-defined projects get a fixed-scope quote with clear milestones. Ongoing product work, maintenance, or evolving requirements are billed hourly or as a monthly retainer with senior developers assigned directly to your account.

Sitecore suits large content-heavy enterprise sites needing personalization; NopCommerce fits dedicated e-commerce stores; DNN works well for portals and intranets needing flexible module customization. We'll recommend one after reviewing your current stack and goals.

Yes. We sign an NDA before any detailed discussion of your codebase, data, or business logic -- just ask when you reach out and we'll send one over before the call.

A marketing website typically takes 3-6 weeks; a custom .NET application, mobile app or AI integration usually runs 2-4 months depending on scope and integrations. You'll get a realistic timeline as part of your project estimate.

Yes -- ongoing maintenance, monitoring, and support retainers are available for every service line, including legacy .NET systems and CMS platforms we didn't originally build.
