Custom Calculator for a Joomla Website

Hi,

I'd like an online bet calculator which can be integrated into my Joomla website.

Here are some examples of the type of thing I'm after -

http://www.oddschecker.com/betting-tools/bet-calculator.html
http://www.free-bet-calculator.co.uk/

I have a few extra things I'd like to be included but in general they give a good idea of what I'm after. I'll provide the calculations/formulas that are needed for each bet type. These can be provided in the form of code (visual basic), so a knowledge of the calculations isn't needed.

Style wise it should obviously fit in with the website and be easy to use, but I'll give more guidance on that when started.

As I've mentioned it needs to be developed using Joomla. Obviously a good knowledge of required skills (HTML,PHP,Javascript etc). If you have examples of similar work you have done that would be helpful.

Get in touch if you have any other questions,

Thanks, Nick
