Consult on migrating items to service now

We are looking for an experienced consultant to help us with migrating our items to ServiceNow. We are currently using Sharepoint as our system and have a customer request to migrate those items over to ServiceNow. The number of items we need to migrate in total is more than 500. We need assistance from a consultant who is highly skilled in transitioning items from our current system to ServiceNow. The ideal candidate must have a solid understanding of both ServiceNow and Sharepoint, and should be able to provide advice on the best possible course of action to transition our items to ServiceNow in a manner that is both smooth and efficient. We look forward to finding an experienced consultant for this task.
