Hello - I could use some assistance if anyone has done this before

We have 3 web portals and each of these portals have a single user/pass and when you connect it only has 4 options:

1) Customer Orders - PO for last 90 days 

2) Customer Orders - PO Search

3) Inventory - Customer Part number

4) Inventory - company part Number 

All of this data resides in SAGE 100

We are looking to build this exact same system just moving it to a different url.

If you have done this before please let me know if this is a project you would be interested in

Thank you

Chas
