DFW DMV Title Service Recommendation Dallas County

I am looking for a recommendation for a full service title service that will come to the office, pick up the paperwork, go to the DMV, and get things done.

One is " easy " take title, insurance, and register it, bring back new plates and registration sticker

Second is "more complicated", as car was purchased from a non-franchise dealer in AZ. Title service will need to take all sales transaction documents, insurance, etc and register car, with our personalized plate, and bring back executed forms and registration sticker. The complication on this one is that sales tax was paid to selling AZ dealer but Texas DMV is not taking sales documents as proof taxes were paid. We need help knowing what is actually needed from someone in the know, as the DMV representative, was iffy to say the least, but refused to help further.

Time is the issue, heck the DMV is 3 minutes from the office, but we don't have the time to stand in line.

If you have a title service you can recommend, please let me know!

Otherwise, god help the DMV person when Pantea has to go herself..
