Develop a "design your own sports kit" feature for a website

I am working on a website for a UK sports kit manufacturer. On this site they want to offer customers the ability to design their own sports kit for their team before ordering. I am building the website in Woocommerce.

What I need is someone to build the kit design feature. Here are a couple of sites which offer this kind of feature:

http://teamwear.kooga.com.au/index.php/kit-designer

http://www.viper10.com/kitbuilder

Ideally I need something which offers the same functionality as these, but better :). There will be kits for soccer, basketball, netball, rugby and hockey. There will be 9 pre designed kits for each sport (eg with stripes, hoops etc).

The process should be:

1) Choose sport
2) Choose kit
3) Choose overlay pattern (see Kooga site)
4) Choose colour 1
5) Choose colour 2
6) Choose colour 3
7) Add logo (via upload)
8) Save kit ready to order.

It would be good if there was an admin area where we can load the initial designs, although this doesn't need to be anything too complex.

I can provide a PSD to work from, just need the coding done. Ideally I don't want to use Flash, but will consider it if you think its better suited. Timescales I will take your advice, but I need it fairly soon. I had hired someone to do it a month ago but they have let me down.

Any questions please let me know! I'm not around much next week, but will try and reply as soon as I can.

Thanks,
Jason

**UPDATE - I am off work for a week at the moment so will reply to any questions on my return, thank you**
