Vlookup and sumifs or pivot table?

hi guys
Here's a tuff one
My clients pays me a fee every month for the service i provide to them.
I have several teams who are working on its project.
Each person has a cost per hour.
If i have total hours worked for each person on each client, knowing what is his cost per month for workers and clients, i may know if i'm charging too much or too litle for each client, right?

That's what i wanna know.

I have my database with how many hours for each person worked on each client. Each person has a monthly hour cost as well as each client.

To obtain the final output that i want, see file attach please, what's your best choice to solve this?

Best regards
Pedro
