Intermediate Calculus Project

I am seeking a knowledgeable freelancer skilled in Calculus to develop a programming project for me. This should be able to integrate and differentiate inputted expressions, and also evaluate derivative functions, eg: x^2's derivative function is 2x. It should also be able to calculate indefinite integrals, and definite integrals using python. It should plot a graph for each expression the user inputs. There should be an on-screen keyboard allowing them to type mathematical symbols onto the solver [It should have a GUI, with a main menu, which lists the functions - integration, differentiation and summations, as clickable buttons. When each button is clicked on, it should lead to a separate interface where the user can input expressions to be integrated/differentiated/summated etc]. The most important part of it is that it should come with a camera icon too, where the user can upload an image into each function section, and then there should be handwriting recognition software which can recognise what it says and can evaluate the function. A WEBSITE IS NOT NEEDED - JUST A PYTHON PROGRAM WITH A GUI
