virtuemart hack to custom stock control with multiple variants

well i have very good knoweledge on joomla and virtuemart 2 but what i m about to do my skills isnt enough also the new virtuemart doesnt help a lot because of the new custom fields it s too complicated to build sth like i wanted... so my hope is in freelancer.com... i ll try to explain my project as much better (sorry for my english im from greece)... first of all my project is a shoe e-commerce site... with offcourse stock control on every single product color and size.... the special need is that every shoe maybe has 5 color each color has 8-14 sizes (depends of the type men or woman shoe) and eash of them has construction material (leather or suede or etc) also if it is woman shoe maybe it has heel height and offcource brand of every shoe and maybe some other attributes.... vm2 has the option to have custom fields with stock control if you choose type of custom field plugin and then with stock control but it doesnt work correctly or doesnt work at all i think that you must already knew that... i also notice that the virtuemart specific custom field doesnt work with sub children products so that i can separete them the children products to color the sub children of thoose to sizes etc... yeap that doent do that trick... and if some how manage to do that it is very complicated the all process to add a product with all it variants... because if a shoe has two color and each color has 6 size at least then i have to make almost 24 children and sub children products so on my levels with a stock about 2000 shoes i have to add products until the next year.. so i need suggestions how we can rebuild the all process ... now to the juice one... lets say we maage to build this hack and proceed with the shop... i want on the product details page of the product to have drop down menu with the available colors and sizes... and offcourse if i change from the color dropdown menu the color then the products details must change (image, description , etc) to the other color... and from the second drop down menu (sizes) must be counting the stock so for example if im in a show red the user must be able to see in the red how much stock is available on each size and if not available to be not has the possibility to add it on the cart.... my standar website i love because it has all the parametrs i want for example you can see here: [login to view URL]%CE%93%CF%85%CE%BD%CE%B1%CE%B9%CE%BA%CE%B5%CE%B9%CE%B1_%CE%B3%CF%8C%CE%B2%CE%B5%CF%82_%CF%86%CE%B9%CE%AC%CF%80%CE%[login to view URL] this is a product detail page how i want it you can see on the right down corner what i m talking about above... the stock on each order must be decreasing... and some how i must be able to easy see my stock levels on eash shoe size and color back to the admin... ok that is all to the stock and variant of the products and how the admin should me add them on the backend i leave that to your ideas... (ofcourse i do not want the hack to affect on any how the original modules of virtuemart such as featured products, random etc... lets see now the user friendly sorting results... i need with the hack a module such as cherry picker module for virtuemart that does sorting results(filtering string attributes) the same way it works but with our above hack... what do i mean ... if you see here..: [login to view URL]%CE%93%CF%85%CE%BD%CE%B1%CE%B9%CE%BA%CE%B5%CE%AF%CE%B1_%CE%A0%CE%B1%CF%80%CE%BF%CF%8D%CF%84%CF%83%CE%B9%CE%B1_%CE%93%CF%8C%CE%B2%CE%B5%CF%[login to view URL]@849355@&LastSelectionId=405 you will that on the left column is tha all idea what do i mean... the user can choose from that module what specific variant of shoe can see such as his size the color he want the category maybe the heel height and etc and the core is sorting the results... this is easy with cherry picker and string custom field type but it doesnt has stock... so i need this too package with the all hack idea... waiting for you...
