I am considering moving my website "aluxurygift4you.com" from Easywebstore to EKM Powershop to try and obtain a more professional looking site.
It depends what you mean by "a more professional looking site". It could mean many things: technology, features, conversion, traffic, sales, seo, etc although I'm guessing you mean cosmetics/visuals.
The thing to bear in mind with all DIY ecommerce sitebuilder solutions is that the person ultimately designing the site is you, not a design professional, and the person structuring the shop for SEO is you, not an SEO professional.
Personally, I don't think there is much difference between the 2 solutions, they are both pretty good (and I'm saying that as a competitor in the
ecommerce solution market), and if you have a look at sites made with either system you will notice similarities (more so in technology, SEO, features, etc). I also do not think that your site is that bad, and there are still things you can do with your existing site to make it more professional, as I have mentioned in a
previous thread (e.g. get a graphic design professional to design the top banner).
Looking at both supplier's websites I must admit that EKM website does look more professional than easywebstore website, but the important thing is what their end client websites look like. If you are thinking you might do better with EKM is that because EKM have been marketing themselves to you and other Easywebstore clients, it might be worth reading what EasyWebstore have to say about this, so at least you get both sides of the story:

Also are there any implications I should be aware of i.e.from an SEO perspective-I only launched my site on the Internet on 1 September 2007?
Unless you're getting a lot of traffic and doing very well ranking for certain important terms, and the money is flowing in (which I guess it isn't since you are thinking of changing ecommerce suppliers) then there shouldn't be too many issues. The main thing with moving is to make sure there is a 404 error handler on the new site during the transition, so that if people click on old site links in google that aren't on your current site, then at least you have a friendly message waiting for them. Eventually the old links in google will be replaced with the new links of your new site.
