Re: Web 2 print system
It's difficult to comment on pricing, but as an estimate, I would say iWay would cost around £30K, which should include consultancy, installation and training to get you up and running live. EFI offer Digital StoreFront, which ranges from £7K to about £14K. I'm not sure what is included in these prices. The £7K version is a simple 1 skin site to allow users to submit print jobs. the more expensive version allows you to create more skins if you want to provide a personal service to each of your customers. I get the impression that iWay offers more out of the box than DSF and can be more tailored to your business ie. for extra money, you can use their Professional services to integrate iWay into your business specific applications, including database systems etc.
iWay allows you to create default templates for each user that logs in and allows you to give the customer the ability to create their own templates. You can charge for this or use as a freebie to tie in your customers.
Please note that the prices I have provided are just estimates and may well me much more for your specific requirements. If I was you, I would checkout the next digital/print show to get a feel for the product and to ask quectios about pricing. I think there is one in 16th-18th OCtober in London.
