I need to get broadband installed at two of our offices to allow shared access to our main database which is written in FileMaker. I think we can probably get away with a 512kb line but worst case a 1mb line because access from the second office will be quite light. I also want to make use of the WebCompanion feature so that roaming staff can check / enter orders over the web. This should not be a bandwidth problem either since web access will generally be outside office hours.
I know I need a static IP but am not sure what else will be necessary. I have looked at a few providers with prices varying between about £20 and £120 per month. I obviously would like a solid, reliable service but I also want to keep costs to a minimum.
