Just wondering, what's the average price for people to do the following?

1. Photoshoot before the marriage (10k?)
2. The dinner (40k can cover all?)
3. The money to the in laws (What's the market rate now?)

It would depend on what you are after, cause everyone want/"need" something different/more/less.

1. Pre-wedding photography, you can engage freelance and bring/provide your own clothing | the more common and pricier (most likely) alternative is engaging those wedding photo studio, where they will arrange the photographer and you can/have to rent their gowns/attire. Price really varies depending on what you want.

2. How many pax are you catering for? Restaurant or Hotel? Perhaps buffet spread at your new home or rent a public Hall?

3. This is super subjective, and you will need to communicate strongly with your other-half. Say the market rate is 100k, and you can't afford that ridiculous sum, surely you won't follow (unless you are MO1 and money is never ever an issue) - the best is to discuss with your future spouse on what your in-laws will be expecting and most importantly, set a ceiling for yourself so you don't bust your bank.

Cheers!
