Excel into DB with complex calculations

I am looking for a freelancer who can transfer data from Excel to a database, performing complex calculations using custom scripts. The ideal candidate should have experience in data migration and database management, as well as knowledge of scripting languages. The project requires transferring both text and number data. The database can be either SQL or NoSQL, but I am open to suggestions. The freelancer must have excellent communication skills and be able to work within tight deadlines.
