Hello there,
I thoroughly tour your description and got precise understanding of your requirement:
1. Logancee theme to be used, you will provide us.
2. B2B and B2C options with easy to use filters as mentioned.
3. Pricing common for B2B, varies for B2C as per 3 tier architecture.
4. Reward system, providing additional discount.
5. Integration with mentioned apps and current website.
But I have few questions, please if you can answer:
1. What all customization needed in the theme?
2. As you said, "pricing and purchasing is only available to clients", whom do you refer as client? Do you mean trade customers only OR trade customers and registered users ready to make a purchase?
3. Who all can leave review? Only individual OR both individual and trade customers?
4. Which payment gateway you would like to integrate?
5. Which is your preferred shipping method?
Answers to these will be helpful.
Regarding suggestion as on Magento loyalty module to be used, I prefer if we can discuss it in PM, so that I can explain myself better for selecting particular loyalty module.
Let's discuss details in PM, and my team is ready to work on this project. I am also available to have a conference with you. Let me know your thoughts!
Regards
Sagar P.
