Sales Template Recommendations

I’m looking for recommendations on a sales landing page template for WordPress (my apologies if this is not the correct forum for asking for that kind of help).

Here’s the problem I’m trying to solve…I have an existing WordPress blog site that has over 100 blog articles in it that feeds traffic to my online training school which is hosted by Teachable that has (7) different training courses. Teachable has a decent capability for marketing individual courses but I want to put the emphasis on selling the complete curriculum and Teachable has only a limited capability for doing that.

Someone suggested to me that I develop a landing/sales page in WordPress that would be a front-end to my Teachable school and I think that’s a good idea since I already have a WordPress blog site and I’m very familiar with WordPress. I would appreciate any recommendations anyone has on how to do this. Are there any sales and landing page templates for WordPress that you would recommend? Can I integrate this with my blog site or do I need to create a new WordPress site for this?

Thanks,
