Used AwlGrip 2 years ago - still looks great. (But I had to leave it in Malaysia - long story there).
Not cheap - and the finish is all about preparation, preparation, preparation.
Which is a lot of persperation! And don't get that in the paint!
Where is it and is Mexico an option for your labor? Or DIY?
Have seen some good 10 foot work using roll-and-tip - still takes preparation and a good 2 sets of hands.
Best of luck - sounds like another money sucking hobby you've got too.
