Hi :-)
You could try Boots. I do know that some time ago it was possible to have any old photo reproduced without the negative. If that's the case, then it's no different than them profesionally scanning it for you.
Bear in mind that the process is only once; so you are looking at 8 - 10 pictures processed once then simply copied to make up the numbers of each copy you require.
A scanner is a good option, but also bear in mind that there are both good and bad picture scanners; in short, you get what you pay for. Having it done profesionally you can be sure of the best possible conversion to digital. Cost and affordability will be, of course, the facter in what you decide should the service be available.
I hope that helps and I think you might find they will still do that service.
