Create jingles for a webradio

Hello. Attached are some files i want you to use to create some jingles. i need 3 jingles. However one of those needs to be done in the way that i can just add some songs before the jingle on Audacity and make it work by my own.. I mean that the jingle says: "Stay tuned cause this hit is coming.." so i just want you to add some music and add some effects on this part so . Also there is another one jingle with the same way.. it goes like: " In this radio we play music from the present.." then it will play some present hits.. "But also from the past" and then some past hits.. "but we are the radio of the future so stay tuned here" so i want this the same way. The last hit is just for you to add music and effects on it. no need to make something else.
