How expensive is an iphone screen repair?

I have the IPhone 6 and I'm just stressing because I have a trip in three days and my phone had to crack on New Year's Eve. I don't have much money to just spend on other stuff, and so I'm just wondering if anyone has done so how much is a screen repair? I was thinking about a new phone but I don't know since I'm spending more money in the long run. Also long time ago I got my IPad screen repaired and it resulted in my iPad to start acting up such as sometimes it would press things I didn't touch or wouldn't react to my touch (but I'm thinking maybe it was just a bad job?) anyway thanks.

Good names for a technology repair business?

I help people fix issues with iPhones, iPods, iPads, laptop/desktop computers, tablets, and other technology.

I also teach them things like how to browse the internet, send an email, organize documents/photos, download an app, and complete other tasks on a computer, tablet/iPad, or mobile phone.

I'm looking for suggestions for a name for my business.

Example I once found on a website…

Name: Check Power Cord First

Slogan: Check power cord first then call us.

How much is an Iphone if I just transfer carrier?

Hi I'm kind of new to the whole deal of buying Iphones because I never did it lol.
My Ipad has one of the old AT&T Unlimited Data plans that stopped being offered but we continuously pay each month to have it. I want to get a new Iphone probably a 7 plus because I barely have storage in my regular one. Is an IPhone still going to cost $600+ if I just try to transfer my AT&T deal from the Ipad to the Iphone? I get confused with the cost because it's always under a plan. Sorry if this question is stupid lol.
