Renewing Wedding Vows

Please help me, my husband and I want to renew our vows November on our 25th wedding anniversary. Our 1st was at the JOP due to his father not thinking I was right for him. We do want to wear a tux for him and a long formal dress for me ( not white). Our 3 children are grown and we have 2 grandchildren a boy 2 and a girl 3 and we would love to include them. We have very little money and this is to be a church renwal wedding. I am still a bit shy also so this will be very small, not many guests. Please help with any ideas, the time is coming up so fast! Thanks, Debbie in Missippippi
