Opencart programmer required for alterations v:1.4.7

Hi,

We need an OPENCART specialist programmer to do some alterations to a bespoke section of an opencart website. We are using v:1.4.7

There are two possible options of what we need doing. At the moment there is an image of a product on the left hand side and options that customers can select on the right hand side. As customers change their preferences on the rh side it changes the image on the left. We need the layout of this bespoke section moved around eg. half the selectable options above the image, the image in the middle and half the options underneath.

2nd option would be a floating image that scrolls up and down as you scroll up and down the page to select your options. Basically to make it so that the image is always visable while you are choosing your options.

I can send the website link but cant post it on here as confidentiality is important at the moment. Please feel free to send me a private message for more information.
We need a costing estimate and a timeframe to complete asap.

Kind Regards
Sam
