If so, what sites out there are good for that?

I currently work through an in-home care facility. But the family I work for is transferring to a new company, and I need a CPR/First Aid certification to be hired there. I took a first-aid training class that qualified me to work at the current company, but it wasn't a full class that gave me a certification. I have taken classes on First Aid/CPR in the past, but never went through with the certification with them before. The other employees have said they got their CPR certification online.
The family is transferring around January 15th, and I need it done by then.
