I need a vpn? need a bit of help

Hi there, I am a small time youtuber that has run into a wee bit of trouble.At times, there are users that D-Dos myself which as i assume most of you know, knocks me off for a period of time. From my understanding A vpn will help protect me from such attacks. My interenet service provider will not help me at all with obtaining a vpn. In my touch screen router I have a Vpn Setting, however I do not know how to fill out the fields. I have had a look at the free vpn services out there, however from past experiences, when somethings free, it's either sh*t or veryunreliable.I do not want to spend an arm and a leg, so I was wondering if anyone in these forums had any recommendations??My skype is Dextereysink, It would be great to hear from someone on there in regards to this as well :)I appreciate you all taking the time to read this and help me out. Thanks againDexter. By the way my routers options have these sorts of fields... + more which is confusing for me lol
