I've been coding VB6 since 1989. ALso VB.net for the last 6 years.
Initally started with VB5 against Mainframe databases via middleware then subsequently MS Access, MSSQL, MySQL and Sqlite.
I worked for a company for 2 years that sells one of the major cost planning suites so i know a bit about cost planning.
I work as a permanent coder for a software but am able to do projects in my own time.
Obviously I'd need to know a lot more about the project before i could agree to any timescales. I set the bid at the maximum but given the budget i assume the amount of enhancement is not too much?
