Thanks for your help.
The first 2 companies don't seem to be able to help (the second has great potential but most of it's Lego stock is out of stock and they sell with much higher price than can be even found in eBay.
I am checking the third one now.
By the way - if you or someone else has a recomendation on what I should sell on eBay - i am open for suggestions -
Thanks a lot
