b2b portal for waste exchange

Well we're from Italy so we have 60 pages with all details about the project but they are wrote in italian. Anyway probably we could find a solution without the deep description. We have a b2b web site focused on waste stock exchange - we cannot insert its address for the terms service but probably it could be useful for explain - we have to upgrade it but we cannot modify the original so we have to rebuild it. We did the first version in 1999 now time's changed and it's easier to find good developper to do a good b2b portal and we believe probably is easier to get something ready and modify than starting to project something new. We check several web site all around and we notice that there are a lot of alibaba clones. So we think that is possible find someone that can provide us with similar solution. A portal like alibaba or [login to view URL] is ok for us. We need a solution like csm that we can completely manages from here. Please contactus for any further question about it. All the best Mauro Pieri
