PHP Quartic Equation Calculator

I need a calculator that takes 5 inputs:

A, B, C, D, E

The quartic equation is: a X4 + bX 3 + cX2 + dX + e = 0

The calculator needs to be written in PHP. Before I will accept the calculator as finished I will need to be able to test it. After testing is complete and the payment is processed I expect full ownership of the code, and I do not want it being used in other places.

I also need this calculator done within a couple of days, the sooner the better. The calculator should not be that difficult for someone that is pretty handy with math AND PHP.

Some resources to research the equation itself:

The code must be on a separate page, and accept values using the POST method, the variables will be passed from a 2nd page with the names "a", "b", "c", "d", and "e". Basic error checking should be used, at the very least the first check needs to be to see if the variable is set, then it needs to check that a value has been entered for each variable.

Please note that no graphics are required. I will integrate the script with my existing site. As long as there is a variable such as $solution I can even output the results myself, just need the "guts" of the code to come up with the proper solution.
