Build a probability calculator

Hi, I'm looking for someone to build me a probability calculator that will help me assess the odds of a specific stock reaching a certain price by a certain date, based on a handful of inputs. I'm currently in the financial newsletter publishing business and this "tool" (the probability calculator) will help my newsletter readers and myself with our stock picking decisions. Yes, there are free probability calculators on the web that we can use, but the one you build for me needs to be specific and for my own website's use (need to be branded with our company name). I'm going to post a picture of what I want it to look like, so please see the uploaded photo. The inputs, which you'll be able to see in the picture, will include 9 user-defined boxes. The first input only needs to be for stocks, so a drop-down menu is not needed. The "future date" box and the "days ahead" box need to be tied together, so if one of those inputs change, the other will change too. The "future volatility" box is usually expressed as a percentage number in practice, but for this calculator, it will be expressed as a whole number. Some of the other inputs are optional, but I still need them. The output section at the bottom of the calculator (in the picture) needs to be exactly as seen. My website - [login to view URL] - is geared towards stock & stock option investors. I don't know what kind of coding skills are necessary for this project, but possibly understanding probability & statistics might be helpful, in addition to whatever coding skills are needed to build this thing. Having a look free probability calculators on the web might help you if needed to get an idea of what they do and what they're used for. I hope you can help with this project, and please contact me with any additional questions.
