Combining 2 SUMS in MySQL and optimising query - mysql

Question

I have the below code which works:
SELECT admin_teams.name,
SUM(temp_orders.amount_paid) as amount,
SUM(instalments.amount) as amount2
FROM temp_orders
LEFT JOIN admin_teams
ON admin_teams.id = temp_orders.team
LEFT JOIN instalments
ON instalments.order_id = temp_orders.order_id
WHERE
(DATE(temp_orders.date_paid) = CURDATE()
OR DATE(instalments.date_paid) = CURDATE())
AND (temp_orders.pay_status = 4
OR instalments.pay_status = 4)
GROUP BY temp_orders.team
ORDER BY temp_orders.team ASC
LIMIT 5
It produces a table that looks like:
+-------------+--------+---------+
| name | amount | amount2 |
+-------------+--------+---------+
| team name 1 | 100 | 150 |
| team name 2 | 200 | 250 |
| team name 3 | 300 | 175 |
+-------------+--------+---------+
I have two issues;
I actually only want one column which is the sum of amount and amount2.
The query is VERY slow - this took 190 sec to run.
I did have it almost working with a Union which was almost instant - I couldn't however get it fully working because the number of columns in my first select statement will not match those in the second - the table 'instalments' does not have a team column but the table temp_orders does.
Can anyone help with either problem?
Thanks.

SELECT admin_teams.name,
(SUM(temp_orders.amount_paid) + SUM(instalments.amount)) as amount,
FROM temp_orders
LEFT JOIN admin_teams
ON admin_teams.id = temp_orders.team
LEFT JOIN instalments
ON instalments.order_id = temp_orders.order_id
WHERE
temp_orders.date_paid >= CURDATE()
OR instalments.date_paid >= CURDATE())
AND (temp_orders.pay_status = 4
OR instalments.pay_status = 4)
GROUP BY temp_orders.team
ORDER BY temp_orders.team ASC
LIMIT 5
And add these indexes
ALTER TABLE temp_orders ADD KEY (date_paid ,pay_status,team);
ALTER TABLE instalments ADD KEY (date_paid ,pay_status);
