User form on the web

[dwright16]

Hi I've wriiten a financial model that's intended to be used in the renewable energy sector. I'm looking to create an input screen on a web site where a user can input information that will link to the model and post results based on the inputs. I'm a financial analyst and excel power user(one-trick pony), but have no idea about building applications on the net. Can anyone point me in the right direction? An article to read? What type of company to contact? Questions to ask?

Thanks, Dave
