Design 3D Logo for a tech company

My Company name - Nirjal Group Colour - Your choice Expectation - It should look very professional, it should not look like a funky logo or a logo for startup. It should have a corporate touch. And most important thing - The name of company should be very very very clear in logo, its help in promotion. So, rather than giving any big image, try to play with letters like "TATA group" or if you want to give any image then please keep in mind that the name of company should be very very very clear in logo. About - Its not a specific company, Its a business group which has many companies like E-commerce, electrical manufacturing, health care, data centres and many more from completely different different areas. Yaa, one thing is common in all companies and that is- everything is based on advanced and modern technology. Type - A 3D logo (2D is not acceptable) Note:- In my last freelancer account, many people has cheated me and i have lost more than 50000 INR (Indian Rupees). So, this time, firstly you have to make the logo and show me, then i will make the payment. Before that, i will NOT make any milestone, payment and i am not going to award the project unless and until you give me the logos.
