I had a big spiel typed up, but imadje beat me too it Couple of things i will add: For the producing side of things, tomy is probably one of the best people for advice on those questions on here However what you have made sounds more like a DJ mashup promo than a remix as such, which leads on to the copyright issues that were said in the post above this. -Yes, giving a mixtape is one way. Also meeting the manager and having a chat to him directly and let them know you are interested in playing there, maybe in combo with giving mixtape -If club doesn't let you sesh gear when they are closed for practice, maybe hire some gear or borrow some off somebody else for a weekend and sesh it too get yourself confident on the equip before trying to get a gig there (controller DJing does have a different feel to it compared to DJing with CDJs) -As mentioned above, depends on club if you can take your S4 in.
