Hello,
No one in the world can estimate this project. And usually database and performance tuning are the most difficult tasks.
We provide database consultancy as well as development. But do keep in mind, once the database is analyzed, it might need to restructure and hence development might also be needed.
Now, can you tell me project details, its usage and main problem areas please?
After the above are answered, I will get into the detailed ones :)
Note : References to already done similar projects can be sent whenever you request.
