You can order these from Daraz.pk via its mobile app. Add discount code "app1000" to get rs. 1000/- discount on these. Google daraz mobile app discount procedure for more info. Each will cost you around rs. 15500/- (with discount) and they are "too good options" in this price.
Honor 4C (great camera, and super fast performance, rest P1M is better)
Lenovo Vibe P1M (more useful features, but sufficiently fast performance and good (not great) camera, rest its better than Honor 4C).
Great phones for long term trouble free usage, however, their LCD replacement is expensive. Rs. 6200/- for 4C and rs. 9200/- for P1M. So you have to get a good protective case (magnetic flip cover case) and be careful while using it.
You can also get Huawei Y6 for rs. 13500/- which is very basic and nothing at all good like the above ones, but its LCD replacement costs rs. 3000/- which is very reasonable. Y6 will be enough for your requirements too, but the above ones are A LOT better.
Lenovo A6000 is also good option (better than Y6) in rs. 13500/- but its LCD replacement costs rs. 7500/-.
Lenovos display quality is excellent (almost like a Super AMOLED panel), but their displays are very expensive too.
Display is covered in warranty, but knowing prices helps to make better decisions, as warranty is void if display is broken and you have to pay for the damage repairs.
IMPORTANT NOTE
These replacement costs are "service centre" costs for full display panel, market prices are much lower depending on the quality and condition (brand new or used) of replacement parts. This is just a general info, please re confirm the latest prices while making a final decision, as prices vary from time to time. Most of the times, only front glass replacement is required which is much cheaper than full display panel.
Post updated with additional info.
