Write some Software

I would like VB.NET script that can download files from the internet and place them in the specific network location specified by the user, the scripts operations is to be determined by incode parameters defined. Details below: Example website: [login to view URL] [login to view URL] 00:00:00 Parameter 1 - Website: [login to view URL] - Mandatory field if empty or invalid address error should be produced in a log file on the same directory the script is running from called '[login to view URL]'. Parameter 2 - TabletoRead:[login to view URL] - Mandatory field if empty script should produce error to log Parameter 3 - Exportformat: ?CSV - Mandatory field if empty script should produce error to log Parameter 4 - OrderExport: &sysparm_order_by=number - Mandatory field if empty script should produce error to log Parameter 5 - Exportfields: &sysparm_default_export_fields=all - Mandatory field if empty script should produce error to log Parameter 6 - Exportrestrict1: &sysparm_query=sys_updated_on - Mandatory field if empty script should produce error to log Parameter 7 - Exportrestrict2: %3E%3D Parameter 8 - DateTime: 2016-11-07 00:00:00 - Mandatory field however this to be read from a txt file that will have just the datetime value in it the name of that file should be '[login to view URL]' and the user should be able to specify what directory it's on in the server. Parameter 8: Username - Mandatory field if empty script should produce error to log Parameter 9: Password - Mandatory field if empty script should produce error to log Whenever the script is run and the parameters don't produce errors a history of the urls called should be stored in txt file call '[login to view URL]' with the date time the script was run. Eg: 24/1/2016 23:12:10: [login to view URL] [login to view URL] 00:00:00 The script is to be well commented and have appropriate error checking. The script has to be able to work standalone and work with SSIS see template below: [login to view URL] Please use this template when creating the SSIS version of the script. Maximum amount I will be paying for this script is $80 USD. Thank you.
