PHP based Mini Web chat using NUSOAP Webservice

Hi! I want to create a wsdl NUSOAP based php client server webchat using NUSOAP. Many clients will chat to one server. Its just like a help desk. This will be like a small web messenger. but Please send me demo first then i will select on the bases of this demo because i have already wasted my time with fake or idiot bidders. No need to show portfolio links just Send me demo, which will be a very very simple In it, we will send three names from client page [login to view URL], and server will response by UPPER CASING those strings from [login to view URL] using wsdl object, keep the code very very simple If your demo will be successful then i will select you in seconds. You can bid under the budget, don't bid low to keep the quality low, you can be selected on the bases of your demo. As soon as you send a demo, you can be selected.
