Usually there is a zero or two missing!
I charge between ?10-?20 an hour. I don't mind there not being a price aslong as there are some specifics.
Also this happens every time:
If you make a request and provide detailed specification and it is complete and does everything on that original specification provided. It is finished. You can't say 'Oh but I really want this which I forgot about.' I'm not telepathic and I'm not going to modify a service request till the cows come home. Once it meets the specification it's finished. Sure more money means you can change the specification
