Default What indexing should I use?

I am planning a MiSeq experiment in which I will be doing a PCR mutagenesis of a sequence, with the intention of obtaining just a single mutation in the ~100bp sequence. To do this, I will test 9 different PCR conditions + negative control. The entire sequenced region would be 130-140bp.

I am having a bit of a hard time thinking about indexing my samples. I am not entirely sure that doing a pair-end run would be very useful. From what I've seen, the majority of primer kits only provide 8 forward primers, and I think I'd need a unique forward and reverse primer in order for the alignment to work. Or, I can do single-sided, which I think would be good enough in my case, but how does it work from a sample preparation point of view - do I just use 10 P7 primers and a single P5 primer for all my samples?

I am fairly new to NGS and don't know how any of these choices affects data analysis in the later stage.

Dual Unique Index will not hurt, but single index is enough for MiSeq.
