I personally prefer the second two. That being said, given ghat 25% of your leads come through your website you may want to test each variation to make sure your users respond well to the new design. You should also check how much traffic you're receiving from search engines and prepare for a drop in traffic after launch. If January is a busy season for your business, it might not be the best time for a full redesign. Will these new designs be responsive? I would make sure your new site is mobile friendly.

Honestly, one doesn't really look any better or worse than the other. They'll do just fine. Just make sure you have a web marketing helping you with the transition from the old site to the new. If you don't do it right you can lose a lot of value that has been built up over time.

I personally like this one: http://readysolution.info/marketquotient/index.html

I do design evaluations for my team and i really don't see what is wrong with your original website. If 25% of sale come from the site that is a very very good % to have. The remainder should be focused on sales support and landing pages to increase that turnover on the website.

Instead of changing the look of your website you could have gone (and still should do) with landing pages created specifically for certain demographics, promoted to them and doing a/b testing. Each landing page would ultimately become another selling tool.

Going back to your other pages, be careful of going with that is trending in design. Almost everyone new to websites is creating websites that have 'infinite scroll' layouts with circles for data, etc. Your original website looks professional, full of info which is good for your industry, and clean. The others are beginning to look trendy, run of the mill 'theme' website with too much going on that distracts away from the content data which should be your top priority.

What I would have done is simply enhance some of the categories and sections you have in your original website to drive eyes to certain areas, increased clicks and lowered your bounce rate.
But if I had to reluctantly pick one I would go with: http://readysolution.info/marketquotient/index.html

Good morning,
I'm not a graphic webdesigner, I'm a marketing person and based on my experience I would not change the website, but:
1. focus on bringing more people: you already have a good conversion rate, keep that and increase the absolute sales instead by bringing more visitors
2. making sure you define 3 max 4 target groups with specific needs you can fulfill, and focus on articulating your benefit in a way that it's irresistible to each of them

1 and 2 are very much linked and I can help you with both, if you are interested :) Looking forward talking with you soon,
Serena

I would point specifically to the stage where you create the site map about the whole thing. Why is this stage important you may ask? This is because the web templates make it easier to create layouts quickly, saving a stage in the process, unlike recent history whereby page layouts are created by graphic designers in Photoshop, or other graphic design software, then handed to the Web Developer to try to emulate.
Besides if you do have any questions give me a call: https://clarity.fm/joy-brotonath
