Hello, my name is Pavel and we are Simple Dino s.r.o. You can chcek our references here in our profile portfolio or you can go to our personal website (link in our profile).
As you can see, we have many experience with projects, like the one you want to cooperate on.
If you like our work, feel free to contact us and we can talk about the details and the final price (we need more informations to make a exact price calculation). I understood from your description, that you want to make a first condiguration of your ecommerce solution (configuring the whole system, categories etc. and adding a gateway for PayU).. I also would suggest to make some changes to the template, since the effects, that the template is using are more negative than positive in terms of UX. All the effects are making the website running slower. Once you fill all the content, the website will be really slow on most of the average hardware (cheaper notebook or smartphones). So i would propose, to turn these effects off in the template for the best user experience possible. If you accept our bid, we can do all of these tasks for you in about 4-5 days.
I look forward to our cooperation.
Best regards, Pavel from Simple Dino s.r.o.
