Greeting!
I have gone through your requirements. We can easily do this for you.
I own a small team of 15-designer and developer offering freelancing services to clients for over more than 2 years.
For your project, we will be using several ways like:
1. Db query optimization
2. Multithreading
3. Mecache
Rest will be told over a conversation. The cost is included in the bid proposed.
Are you interested?
Looking forward to your positive response and working with you.
Regards,
