I have plenty experience in SAP B1, also in SQL server and HANA.
I think we have to define the tasks in your project because my offer is only for migration not for installation and developing of the HANA environment.
Crystal Reports may be included in a different project.
I prefer working in milestones, because is clearer for both of us.
Please let me know if you have any doubts or if I can help in any way.
Regards
Augusto
