Online Tax Computation form

I have an MS Excel sheet with 4 separate forms which I need to embed into a website in a relatively secure fashion. The forms would require 4 basic separate mathematical computations respectively, based on user input. We would hope that the project could be completed using HTML possibly incorporating Java/Java script. All formulas are supplied - a basic HTML interface is required which returns a YES/NO answer to the user dependent on the data inputted by the user. This is a simple project which would probably cost an average web developer a few hours work. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
