Sorry I don't recommend proxy providers. It's a tough decision, because anyone I recommend people want me to be responsible for, and it's impossible to be responsible for someone else's service. Plus proxies can be random, you may get a bad IP, or there may be issues, when proxy providers don't reply to support or refuse to accept any responsibility for their service and just want to blame everyone else, I invariable get the support as I do answer support. For the same reason I don't recommend account sellers either. So it's a bit of trial and error to be honest.
As for turn key solutions, if I can provide you a once click solution where you pay $100 but make $100 +(x) with just clicking a button, well I would just be clicking that button all day long.
The analogy I like is, social media marketing is a gold mine. You can strike it rich, many do. But I'm just selling you the equipment, I've not drawing a map, nor doing the digging, nor carrying the gold back to your house for you. Equally, and I won't lie. Digging for gold is difficult, you do not strike gold the first time you push the shovel into the ground. You need to learn the lay of the land, you need to trial and error, you need to find a system that works for you. It can be back breaking labour. But if you stick with it, if you learn ropes, if you learn from your mistakes, the results are there just waiting for you.
