Hi beachdisney,
Google base is a great tool, but more effort needs to be put into establishing a brand and helping buyers feel comfortable buying from you. After viewing your post, here's what we recommend you work on:
1. Product description - you need to write more about your product
2. Product photos - you should provide more photos, maybe you can add a few photos of the golf balls not just the box.
3. Build your rapport or add something about you - since the buyer knows nothing about you, they may be a little apprehensive and not willing to trust you and your product.
We recommend setting up a free website as well, here's a blog post that may help:

A website will let you talk about yourself and your business and provide further information on your policies, with an FAQ, Contact page, photo of you and your business etc. All these things help put buyers at ease. Plus it will allow you to scale your business faster and most of these options have functionality for automatically submitting your listings to Google.
Hope this helps! Good luck! :)
