Experienced WordPress/WooCommerce Developer Required

General information for the website: Create your own Salad, Burrito or Pasta from available ingredients
Kind of development: Customization of existing website
Num. of web pages/modules: 3
Description of every page/module: The modules I have used for the site are as follows;

WooCommerce

WooCommerce Composite Products

WooCommerce Product Bundles
Description of requirements/features: I am web designer and I build bespoke websites for my clients. I have a fair amount of experience in this field so please bear this in mind when you post for the job.

The website in question www.saladjunction.co.uk is custom built using WordPress and WooCommerce along with the aforementioned modules installed to allow the customer to build their own Salad, Burrito or Pasta dish. The site is live now so you can try out the functionality by following the link. I have done some modification to the plugins such as using Jquery-UI to create the tabs for each stage and custom CSS.

Also the products are set up in a possible complicated way in the back office in order to achieve what you see on the live site, if you need access to the back office before quoting or accepting the job please let me know.

The work I am looking for somebody to help me out with is as follows;

Currently when you select an ingredient from the Ingredients tab on any of the product creators they are all Free. I would like the first 3 ingredients selected to be Free then any subsequent ingredients should be charged at 50p (might alter) each, the sub-total price should update with the selection of each extra ingredient also.

The next part is dependant on whether a customer selects the Medium or Large options on the Salad and Pasta products. If the Medium size is selected then 3 options from the Deli tab are allowed to be selected maximum. If the customer selects the Large option then 5 options are allowed from the Deli tab.

The work is time sensitive and I am looking for the work to be completed within 7 days.

I do quite a few of these types of website so ideally I am looking for someone who I can keep working with in the future. I have used PPH before but I am yet to find a really solid and reliable developer so please get in touch if you are able to help.

Looking forward to hearing from you.
Extra notes: Please take a look at the site (www.saladjunction.co.uk) and try familiarise yourself with how it functions. If my budget is not accurate please let me know and state why and have a counter offer for the work for me to consider.
