Drugs Database

Hi I am looking for a software to keep track of drugs in inventory, prescription of drugs, medical store drugs balance. e.g doctor has written a prescription slip and patient has come to pharmacy, there pharmacist should just enter menu down search boxes, he should not need to write anything and should be able to choose everything from menu down boxes. prescription date: menu down date/month/year (for that day date should be there automatically) registeration number of slip box one opd: medicine, [login to view URL] etc. box two: tab, cap, syp, gel etc, box 3:alphabetical drugs name, e.g. if he want to enter paracetamol, then writing p should bring all drugs with p alphabetically so that he can select easily. box 4: dosage like OD, BD, TDS etc. box 5: 1-30 for many days to give prescription then enter and print if he likes, then for whole record for that day in the end of day with one click should come for printing and storage. and every prescription should make that drug less from his earlier balance, so in the end when he sees expense he should be able to see balance of drugs also, and he should be able to take print or record of any number of days, months or years. and in the hospital in which i work, there is a special number for every drug, he should not need to enter that number but when takes print or sees record that number should be there for that drug in the row. anyone for this project please quote your price.
