HEY DAVID
Hello, nice to meet you!
Have skilled specialists to handle with your requiremets for teachers, visitors and admin.
To estimate an amount of work we need to discuss more info - welcome to private messages.
Payment - we are working on a milestone basis. Before the project gets started, we create milestones in the system and split the project cost between them. Once a milestone is completed on our end, you review the delivered chunk of work and, if everything works, approve it and release the said milestone payment. Then we move to the next milestone and so on.
If you are ready to talk - waiting for you.
