Gareth_Gillman saidIf you do it yourself you could have it sorted for less than £100 e.g.
- theme from themeforest, upto £40
- web hosting - upto £40 a year
- plugins from codecanyon if you need them
There is no cheaper solution than putting together a WP site with woo and a tablet to read the orders off, simple to do.
I 100% agree (most of our customers run WooCommerce), but I would recommend not to go for a cheap hosting. Any managed WordPress hosting would provide a much better experience, and it would be only marginally more expensive.
