For one of my sites I want to set up a service whereby people can set up a permanaent keyword query at the National Library of Medicine database (MEDLINE) for new medical research.

The database is at:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi

The will get a daily email when a new reference gets added to the MEDLINE database.

There is a similar service run from here:
http://pubcrawler.gen.tcd.ie/

Here is how it should work - they come to my site, register with their email and the keywords they want to monitor and get daily info on (eg kidney disease; kidney dialysis; renal stones) - on a daily basis a search is made of the MEDLINE database by the script and an email is sent to the person when some new articles are published on that topic - a link in the email takes them back to their page on my site with links to the MEDLINE articles, similar to the one linked above:
http://pubcrawler.gen.tcd.ie/pubcrawler_output.html

I have some drug companies interested in sponsoring a site like this. A lot of the search query's may have new articles daily - others will only be added to sparodically.

This is way out of my league to develop, so am collecting ideas/background at the moment.

I have also posted a similar message in the freelancer forum, so am looking for help to develop this - not sure who would be best approached to develop this.
