Thanks for the replies everyone - it's nice to know that i'm on the right track with this!
Is it permissable to post on here to ask if there are any developers who might be interested in taking this on as a paid project, or am I likely to get kicked off the forum?!
I'd like to get it done fairly speedily and at present I just don't have enough knowledge of the programming languages involved to get the project to the point I need it to be at.
Thanks
Rob
