At very first I wasn’t so sure when we first found priyo purely because he was over in India and we are in the UK, but we first used him for upgrading our opencart from 2.2 > 2.3, he completed this within a couple of days and it worked flawlessly.
Ever since then we have used Priyo for absolutely anything to do with opencart from us breaking our website when experimenting with new things to installing an extension properly and we even use him to make any extensions we require before shopping around anywhere else now. We are friends on Facebook and he will prioritise our work if ever needed. His prices are extremely cheap too for the amount of time he saves you! We have complete trust in Priyo and all the work he does and I would recommend him to anybody that needs opencart work doing.
