I need a help with a web developing. Can you give me some contacts of a professional in this sphere?

It is popular sphere in a 21st century, so there are many firms and private people who deal with this. I think that you need to find good web developing company, because it costs a lot. I do not understand anything about this, but I make order from https://www.gravum.com/services/dedicated-teams/ which my sister adviced me. They do work related to outsourcing services with a high quality.

What software are you looking for? I have an online store on Shopify and I know how much it costs to create some kind of program for my e-commerce. It's very expensive. In addition, you will need to constantly pay the company developer in order to receive an update or add some features to your program. I don't think that this is beneficial for the business. I found a ready-made solution for my business, I found a tool ready for use by analytics for my online store, here https://www.savvycube.com/shopify-analytics is a full description of this tool. This program fully meets all the business needs that I had and I'm pleased with how this program works. I don't have to pay for an update or technical support, this is included in the price of this software, which I bought from a software developer company with a good reputation and I'm sure that my program doesn't have bugs.
