I have an application that is written in C# using winforms. I need someone to develop a service that will get the zip code and County from an address. There are many of these like melissa data, accumail and others. I am looking for a free service because I only need the zip and county that is it. I cannot pay thousands a year to subscribe to these services. The USPS has a free system but it is an API and you have to register each customer and website, you may also not do any batch updates. I want something that doesn't need updated annually or that costs me a lot of money. I have 200 different customers that have anywhere from 20 to 300 computers inside their organization. As they key in and address I need to be able to get the zip code and county that address is located in. Sounds pretty simple and it is but finding a way to do this cheap or even free isn't. Keep in mind this application need to work in winform not ASP.Net. The service or API can be web based but it has to work in a winforms application. I am posting this again and need it started on as soon as possible. Thanks in advance and good luck bidding.
