Even if you get another Template (& you have been offered some for free from users on this forum, you will still have the same problems, You can't just fill in the blanks or join the dots so to speak, without a modicum of understanding as to how the app works & what to do to get it looking right, & an eye for design (making the look & feel of a site look good for your visitors visual experience) So for example if you replace text with your own, & there is more or less, text than in the template, it will throw out the template design somewhat, Images of different sizes, proportions will throw out the template design also, that's when you need to be able to adjust modify tweak whatever you want to call it, to make the template fit YOUR idea for the layout.
You are also working (I suspect ) from the highest breakpoint, down (which is the way v1.5 did it), which is why your mobile devices don't look too good using RSD v2.5 or SDv3
On RSD & V3 you work from Mobile devices upwards making it look good & fit at those sizes first, changing the layout as required at the breakpoints if require at the higher breakpoints as you move up.
There is one common denominator in all the apps v1.5 rsd v2.d & sdv3 you have tried & tried but still can't look right.
