Hi Juliana, and welcome to the forum!

Forum traffic slows way down this time of year, so it may be several days before you get the responses you're looking for. I am no expert in any way on resurfacing, but I do know that prices very greatly regionally--and you are limited to what providers are available to you. My best advice would be to check with them all and compare among what you have available....you might get much lower price quotes from folks around here, but they're not going to do you much good in Hawaii.
