Most people just use Godaddy just for for domain registration and host elsewhere.
They offer you many options inc WordPress hosting during checkout which you may have signed up for – check your account. This is £3/m yr one, rising to £6/m after for their most most basic service.
If you are semi technical you can get cheaper and manage yourself somewhere like: https://www.tsohost.com/web-hosting/wordpress-hosting (no affiliation / link – many similar, just Google). If you are more technical you can get some great free credit deals with Amazon.
As an SME / indie Dev offering a non technical user a service / support £6/m IMO is fair / inline with Godaddy standard pricing.
Make sure you have server / WPadmin access / credentials in case he disappears / you wish to transfer elsewhere.
