Hi!, I'm a SAP ByDesign consultant and I can help you with this task. You would need in your tenant a developer user, so I can use it for the creation of Web Services (really important).
Relevant Skills and Experience
OData, SOAP, REST, SAP Bydesign
Proposed Milestones
$277 USD - Creation and configuration of Web Services (also, it depends the type and how many)
Is your tenant a production one, or a testing one?
