Hey,
I can do this for you.
I run my own web design and marketing company and I create Shopify stores all the time. In fact, I do way more than that, as I also have a unique service that takes an ordinary person and transforms them into an Influencer then we ... design their brand...build a Shopify store...find winning products...create their ads...store mgmt...smm...ad campaign mgmt...
So we offer a great deal of value to small store owners and we help lots of people achieve success.
I've only this week decided to branch out on to Freelancer, so I haven't had the chance to build a reputation on here, that is why, I'm going to leave the decision on how much to pay me, down to you.
I would have bid $0 so that you are completely free to decide but I can't place a bid lower than $30, so if you want to pay me more, then do and if you're unsatisfied then don't pay me at all - how does that sound?
I'm doing it for the feedback basically, anything else is a bonus.
Anyway, let's get your second domain pointing to your Shopify store.
