woocommerce questions – trying to pic an ecommerce solution

I don’t know of a phone number but you can contact WooThemes directly with pre-sales questions. Go to the site and fill out the contact form.

There are any number of consultants/developers who’d be able to help with specific questions. In fact if you have specific questions you can ask them here in the appropriate format. Of course there’s no guarantee that you’ll get an answer from this free resource.

As to your needs:

1. excellent SEO and Filtering.

I would suggest Yoast’s SEO plugin.

1. great newsletter potential. nothing fancy but I need to be able to have a doctor inform me of a product that he needs or has to sell me and turn the email around to me list quickly and efficiently as this is how i source my used equipment.

WooCommerce doesn’t provide newsletters, you’d need to integrate with another plugin or service.

1. i could have over 1000-2000 products.

2k products isn’t out of line if they are simple products. If you’re dealing with multiple variations on top of the 2k base you may have some performance issues. Depends upon your hosting environment and configuration (i.e. shared hosting, virtual private server, co-location).
