WE need software that will be able to import an excel file. The excel file will have Holder ID column which will be the ID field. Then once a week we want to be able to import another excel file. 1) If the Holder ID does not exist then that record will need to be added to the database. 2) If the Holder ID exists then the software will compre the Shares field and calculate the change and report the +/- difference. 3) We will need a list view, edit, delete fields or records. 4) We must be able to run the software online using msql databse. Escrow will be made one 50% of extraction has been done and shown to me. Payment...! No advanced payments. Escrow only when 50% of the work is done. Final Payment when all issues are fixed and installed. Payment is guaranteed. I am a certified webmaster with a 10/10 review. Payment will only be after all scripts are installed and tested on my server and all bugs are fixed. During project you must be online and available for progress checking. All comunication will ONLY be through ICQ and skype.
