Legit or not?

Someone I know told me that he worked with a couple of guys in india who scaled his online service but creating content and sales funnels and all that stuff and he suggested I use them for my clothing brand. I hopped on a call with him and he offered 500$ down payment and 20% revenue share and he said that if I was not making 10k a month whithin 8 months I would get my money back. They have around 3K followers on insta and everything seems fine on my end but what do you guys think? Too good to be true?
