How much would you say it costs to fix my bike chain and stop it from slipping when I try to pedal quickly or put a little pressure on it?

Thanks for the question. This is not an easy one to answer without seeing the bike. It could be a multitude of reasons; some simple and some more complex if it is an older bike that hasn't had regular maintenance. Could you bring the bike into the shop? Then we could start pinpointing what the issue is and what the cost would be to correct before we start. This way you'll know in advance and can make a more knowledgeable decision.
