Simple, clean a logo that says it all

Cart2Quote

I am an entrepreneur and always thinking about how sales and marketing processes can be more efficient and effective with the use of software.

Now I have developed a piece of software that enables Wholesale and B2B online shops to create and manage Quotations (besides the standard "add to Cart" functionality)

So what I need is a logo for this software product with the name: Cart2Quote
The software is an extension of the populair eCommerce software: Magento

Function of the software
This software extension enables visitors of Magento based shops to create a Request for Quote and enables shopowners to easily propose a price for the requested products and send the Proposal back to the customer. (a complete roundtrip)

Mainly B2B (Business to Business), Wholesale and enterprise eCommerce shopowners will use this software extension.

But I expect a great deal of website developers to visit my site, from all over the world. They will probably be the ones that recommend this product to the shopowners.

Logo look and feel
Check the website layout:

(Choose Lightgreen as color, see attachment)

Keep it simple and clean. Viewers of the logo should understand through the visual that our software can Switch the Normal "Add to Cart" function to a "Add to Quote" function and back again. = "Cart to Quote"

Title "Cart2Quote" easily readable at different sizes of the logo.
Balance between icon and text in logo: icon needs to be clear / crisp, but the name is what needs to stick. So relatively high visual importance of text.

Keep the target group in mind!

Text:
The product title: Cart2Quote
Tagline: The complete Magento Quotation manager
(the logo needs to stand alone form the tagline, giving us the option to show logo with or without logo)

Extra points for creating icons in the same style for:

-Professional/B2B/for-Business
-Complete/Full-Featured/all-processes/Full-roundtrip

Finally: Create impact, be bold, be unique....may the best logo win!
