Budget estimate

$100,000 – $500,000

The budget for this opportunity is difficult to estimate without more information about the scope and complexity of the project. However, based on the fact that the City of Irving is seeking a consulting firm to design and implement APIs for software integration, the budget could be in the range of $100,000 to $500,000. This estimate is based on the assumption that the project will require a team of experienced developers and project managers to design and implement the APIs, and that the project will take several months to complete. Factors that may influence the likely payment range include the complexity of the APIs, the number of systems that need to be integrated, and the level of technical support required.
