Hi.. So far i saw reviews of them, not bad their design quite nice and prices very competitive. Maybe you can contact them all and shortlist them afterwards. Its best you do more research and see if their style fit yours or not. My friend recommended me Elique.co, a design and build consultancy and i paid for their 3D drawings before signing the contract so i can guage whether good or not. So far so good, but still need further research to shortlist more companies. Maybe you can try to ask for 3D drawings first from these companies and see their skills.
