Dear Sir,
I have done a similar job in a Pipe Manufacturing Company where the Accounts module was on PHP and mySQL, and we were creating HR module in .NET. So we created a webservice in PHP and consumed it in ASP.NET. We had to update the HR module whenever salaries were paid. Accounts Department use to pay salaries and the same was updated in HR through a web service.
I have a lot of experience in using Web Services. I would be glad if you could share the entire details and give me an opportunity to work.
Thanks
