Hi, my friend wants to buy a GPU rig (3-4 cards) or share with someone and have more cards (6, 12, ...) and was wondering if there's someone offering not a cloud service but service where you buy parts, let them ship to service provider's address, then they assemble the rig, install all the software, set it to mine with max profitability and keep it in their farm where is cheaper electricity, IT expert nearby, good temperature/humility, secure, enough power, no dust, etc. etc. Googled but didn't really find good solution. Maybe you can help.
In summary, you are looking for someone to build your own mining rig and he'll do all the job, looking for GPU's, setting it up, putting it on rack, etc? What I can't understand is why you don't to place it on your own comfort and why you want others to control your rig. This is risky when you don't know who you are dealing with. On ebay, you can find people who are selling rigs, parts and racks and they'll ship it to your desired address.
Try to check these maybe this will suit your need

Also there is need technically skills.
