Need online arbitrage calculator & webpage creating

General information for the business: Sports betting
Description of every module: Hi

I need to have a simple arbitrage calculator creating that can then be hosted on our wordpress website.

We offer information on arbitrage opportunities using online bookmakers and would like to create a simple to use arbitrage calculator that shows how much someone needs to bet on each outcome to generate a profit.

There are a number of sites using similar programs and I'd be happy to point you in their direction.

We would be looking at both a 2 and 3 entry field options. (So that mans when there is only either 2 outcomes to bet on or 3 - ie Win/Lose in a horse race, versus win, lose, draw on a football match)

The successful bidder will also need to know how to create it so it runs on our wordpress member site

I do need a quick turnaround, preferably delivered by Thursday this week. I will select a successful bidder by 7pm today

If you have any questions, please just ask

Thanks
Lee
