PHP Database developer NEEDED!

My name is Suresh Thurairaja, I am a small to medium business developer and a B2B service provider based in Toronto, Canada. My clientele include mama and papa shops to IT experts. I need a PHP developer for a simple project. Project Overview: A qualified PHP database developer needed, who must also be able to create a user interface to populate the same database. At times, the database will be populated over the internet and other times, more than one users may need access to input information into the database. Therefore, I believe it maybe advantageous to create the user interface using a combination of html and javascript (or CSS), but I am willing to listen to suggestions. Moreover, the user interface must be password protected, and should allow creations of at least 5 different logins with an admin who is able to change these passwords, as needed. The database should include 11 COLUMNS and have the capabilities for including more columns as needed. Creation of a new column(s) should not request information for elements that were already entered into the database prior to the creation of this new column(s). However, new information may be added to the previous parts as needed. User interface should have search capabilities. Search query could be any of the 11 column elements. This database should allow elements to be edited individually. User should not have to delete an entire row in order to edit a single element. In your response, please include your name, qualifications, samples of previous work, and number of days expected to deliver a bug free project. Also, must be available to provide any help with bugs fix-up for 1 year from the project delivery date. Provide your expected compensation for this period as well.
