Basic financial math tutor

I am currently studying for a masters in real estate. Having not studied math since GCSE I am struggling with the financial math component of the course. Looking for a few hours tuition on subjects such as interest rate conversion, IRR and discounted cash flow. I understand the concepts, but struggle to apply them. I have a few questions provided by my university it would be helpful to work through.
Ideally I'd like to do this in person, but I'm open to other methods.
Looking to do this either later this week or next week.
