Re: Would this be a good idea?

I have funds outside of Bitcoin, do you think a service where I buy for things that only accept real cash i.e https://g2a.com, amazon.com or anything else. And I receive Bitcoin?
Obviously escrow can be used, or people can pay upfront, whatever the case is.

Bottom line, is this a good idea?

Yes, it is good so that you can help bitcoin to circulate on the market. Good way also to encourage others to do what you're doing. That's a good start already to help bitcoin develop faster.

Maybe like a network? Anyone can join and just do what I am doing and this will help increase the growth in bitcoin. Good suggestion.

It can help to growing bitcoin in that way.. but i think someone already made that site that you can buy games g2a using their site that accept bitcoin i forgot the name but its already made many games in their website is from g2a.com also in amazon someone already made those service like purse.io..
