Web Design Review from Gregory Kohs 📊
ISKPRO did a really nice job, right from the point of initial contact, through to the point of final deliverable -- plus they made a couple of follow-on recommendations for additional work that could benefit my business. But no "hard sell" on those items. Just how I like it. The team was especially patient with me, because due to some unforeseen interruptions to my schedule, I was not very prompt in keeping the project moving. But they patiently waited at ISKPRO, and I was not charged for any of these delays that I caused (even though I'm sure it was somewhat disruptive for their developer).All in all, a great job -- and their fees were about 60% less than what a local agency would have charged me to do the same work!

Ramez and his team designed a complete over hall of my website when I sold my marketing agency and went into consulting. It is sleek, professional and makes me look good. I'm very happy with the outcome.

I needed someone to move my website over from Wordpress to Shopify and communicated with several providers. Ramez from Lightspace Creative responded very quickly and was very polite and gave out a very positive vibe. His quote was a bit out of my budget but I decided to go with Ramez because he asked all the right questions and put me at ease. I was pleasantly surprised when at the end of the project, Ramez came back and told me he had completed the job in a fraction of the time. He was quick and efficient and in the end, completed the job well within my budget. My website looks great and works marvelously! After he was done with the project, I had some questions about the website, and Ramez took the time to answer them (and so politely too!). I've already recommended Lightspace Creative to several friends for their website needs.
