The price of curating services can greatly vary depending on the complexity of the exhibition, the scope of the project, its length, and the ways in which you would like to collaborate with them.
A curator can offer a very basic package that may include simply writing the exhibition text, help in mounting the exhibition, and opening it. In this case, the price will be significantly lower compared to a collaboration that would include extensive project planning, managing the budget, ensuring the transport of artworks, public relations, organizing additional activities, writing the exhibition text(s), mounting the exhibition, and, finally, opening it and then helping to take it down.
