My Three Grandkids need our help

I don't know where to begin because this very senitive subject.  I would like to protect the privacy of our grandkids.  But I can tell you enough information to know this little angles need our help.    We  gained custody of three grandkids 2 months ago.  Although we thought it was going to be temporary, it looks like it going to be many more months or longer.  There father is in the army stationed in Korea and was not home when this all took place.   He has been informed and knows we have custody of his kids.  They were put in our care to keep them safe from there mother's boyfriend.  My husband and myself are in our 60's but  still working full time. Therefore we have all three kids in full child care when we are at work.   Getting custody of three grandkids age 4,6,8 at our age has been a life changing experience.  We would like to be able to afford to give them best life can bring.   They have been thru a very tramtic experience and deserve more.  We are getting no assistance from family or any other financial support.  I must say they have to be the most wonderful three kids I ever met.  We setting up go fund me page for the children.  Funds will used totally for them.   The camps for summer for two oldest kids is $2,000 dollars a month and bills can add up fast.  The little one is in 5 full days of child care and that is also $190 week or $800 a month. Once camp is over the two oldest one  will be in aftercare and the the little one is going to vpk for 4 years old this fall and after care for her alone after the rebate is applied will run about $150 week.   We both have good jobs but this is a little strain on us and the kids need some financial support.   They are living very comfortable and I do not want to make it sound like they are living in poverty and our home is awesome however there is extra things we would like to provide for them that we just can't afford.  Most important they need thearpy and the two older girls  need to be tested for the gifted program for the start of new fall term.  Each test for each child is about  $500 to get them privately tested for the gifted program.  If I wait for the school to order it I was informed it take over one year.  I don't want waste one year waiting.   I called the state but they do not offer anything for them at this time.     We have wonderful friends who donated clothes and some toys to help get them set here so it feels like home to them . The state donated a bunk bed and now we have set our extra bedroom like a kids room.  All three will stay in one room and they feel safe now.    We will keep them safe and love them and time will heal all internal wounds.  Any help for them will be appreciated.   They are blessing and we are thankful we could bring them into our home and keep them safe. Love heals lots wounds.
