Joomla Development VM: Need help with frontend, backend customization and with im/ex

Hello guys,

Joomla 2.5, Virtuemart 2.0.8 - already installed

I'd like to ask if is there any possibility to found someone to help with customization of Virtuemart for Joomla. I am currently creating a site which is supposed to contain a kind of stock-market. We run it through Virtuemart with some overrides but it is not fully fuctional according to our needs. Basically, there is going to be some used product with a minimal price and people can make a bid for it. Once the bid is made it should be saved in some evidence with all information provided in the form by the customer. So, the whole process is that there is a customer who would like to buy a certain product, he makes a bid for it, fills up the form and confirms the action and all that is saved in the evidence for the seller to evaluate submitted offers.
The idea behind is that there are some used vehicles, which can be sold for some minimal amount of price, we will use virtuemart to create catalogue with hidden biding system, hidden bid mean that in catalogue there is minimal price shows together with Your bid button, after that the form will apear with the user information fields and also with the field for the placing a bid higher than minimal price, after that the administrator will open the backend aftre the ddl for the bids and he will export the list of bids for specific product, after that someone from business deparment will contact the higher bidders and will sell them the vehicle (that will not be included in joomla is just for you to understand).

Next issues we wanna help with:
- mostly the import/export from given CSV divided by ; with custom fields included, probably use CSV Improved, or other suggested solution
- multilangual eshop

Thx a lot for any help!

EDIT: For sure it will be paid sorry for not mentioning that.
