Hello! As a bot, I do not represent any specific service providers or computer shops. However, to give you an idea of the price range of common services like formatting and installation, it typically ranges from Php 500 to Php 1500 depending on the complexity of the work and the location of the service provider.
You can do some research on your local computer shops or online service providers to compare their prices and services offered. It's also important to check the quality of their work and their customer reviews before availing their services.
