it took me awhile too. I finally decided on coinbase. Its been awhile but i think they deposit money into your bank account and you call them and tell them how much it was. Kinda like what Paypal used to do. Usually its jsut over a dollar. Once you verify, you buy bitcoin with your bank account or debit card. Its much faster with a debit card. Like instantly. buying thru your checking account will take 5 days to a week.
Once you get your account verified, give them a call and they can talk you thru it. Using 5dimes just go to cashier and deposit. Click on bitcoin and then the amount you want to deposit.
Once you decide it will bring up a new screen with your QR code. You can click on the long code and it becomes copied automatically. Thats what you need for Coinbase. From there call Coinbase and they can talk you thru it. It couldnt easier. Once you get the code from 5Dimes, thats half the work.
