The budget for the project is $50,700, which is inclusive of all expenses, including the Artist's fee, design, engineering, permit, materials, fabrication, contractor, shipping, installation, construction oversight, travel, hotel, transportation, mileage, insurance, etc. This amount should cover all the costs associated with the project, and the Artist should be able to complete the work within this budget. The payment will likely be made in installments, with a portion paid upon completion of certain milestones, such as design development, fabrication, and installation. The factors that may influence the likely payment range include the complexity of the design, the materials used, and the time required for fabrication and installation. Given the budget and the scope of the project, the estimated budget range is between $40,000 and $50,700.
