New domain name for business - advice needed!

Hello all,

I currently run a business selling handmade leather goods, in particular satchels. We have a decent website and make steady sales, but I think we could get more hits and therefore sales with a better domain name.

Our current domain name is simply the name of the business, which has no relevance to the products we sell (it is just two surnames).

We currently get barely any organic hits other than from people who search the name of our brand/business.

Our best selling product by far is our satchels. From my rudimentary research, I think it would really help our Google ranking to have "satchels" in the domain name. I was just wondering which you think would rank better:

[surname][surname]satchels.com
[x][x]satchels.com - ([x] being out initials)

We want to rank well for:

satchels, leather satchels, handmade leather satchels, school satchels etc.

Any help whatsoever would be hugely appreciated.

Thanks
